   2 Things in SBCL that look like special variables (list created by
   3 (apropos "*")) and could conceivably indicate potental thread safety
   4 issues.  Organised by functional area.
   5
   6 The goals are
   7
   8         (1) classify the unclassified symbols (in such a way as to
   9         make sense for 2)
  10
  11         (2) read through the subsystems identified looking for places
  12         where global state is mutated.  Use this list of symbols as a
  13         guide, but be open to the possibility that other state
  14         (e.g. closures, foreign variables) is touched too.
  15
  16         When looking at a particular symbol, please annotate it in
  17         this file when you figure out what it's for and how it's
  18         changed.  To give us some confidence that we have reasonable
  19         coverage, please don't just delete it if it looks ok.  Symbols
  20         shoud only be deleted here if they're obviously not specials
  21         at all (e.g. functions with * in their names), or if the same
  22         commit actually rids SBCL of the symbol itself (as we may soon
  23         do for e.g. SB-SYS:*TASK-SELF*).  Otherwise, just add a
  24         comment saying "read-only" or "unused" or whatever.
  25
  26         (3) anything else that comes to mind as potential trouble
  27         spots.  Global state in closures, etc etc
  28
  29         (4) suggest strategies (e.g. rewrites of affected code, suitable
  30         locks and lock acquisition/release places) to fix the issues
  31         revealed in (2) and (3)
  32
  33         (5) implement same
  34
  35         Candidates may attempt any of the above simultaneously.
  36         Points will be awarded for style

  39 Summary so far:
  40
  41 = loop
  42 = PCL            (probably ok if PCL authors did *without-interrupts* right)
  43 = debugger
  44 = profiler
  45 = disassembler
  46 = assembler       (I assume protected by *big-compiler-lock*)
  47 = unix interface  (apparently ok)
  48 = toplevel/environment stuff
  49 = the formatter & pretty printer  (two vars need checking)
  50 = compiler        (protected by *big-compiler-lock*)
  51 = fasloader       (protected by *big-compiler-lock*)
  52 = runtime stuff - gc, control stacks, interrupts etc
  53 = backend constants
  54 = dead
  55 = unclassified
  56
  57 ==================
  58
  59 = loop
  60
  61 I suspect that stuff in sb-loop is only ever frobbed at
  62 macroexpand/compile time anyway, so covered by *big-compiler-lock*.
  63 Haven't thought about this too hard, though

 100
 101 The PCL authors thought a bit about thread safety, adding
 102 (without-interrupts ...) in some places to protect critical forms.
 103 We've implemented their without-interrupts macro as an acquitision of
 104 *pcl-lock*, so we hope they've done it properly.
