- :TOPLEVEL
- The function to run when the created core file is resumed.
- The default function handles command line toplevel option
- processing and runs the top level read-eval-print loop. This
- function should not return.
-
- :PURIFY
- If true (the default), do a purifying GC which moves all dynamically
- allocated objects into static space so that they stay pure. This takes
- somewhat longer than the normal GC which is otherwise done, but it's only
- done once, and subsequent GC's will be done less often and will take less
- time in the resulting core file. See PURIFY.
-
- :ROOT-STRUCTURES
- This should be a list of the main entry points in any newly loaded
- systems. This need not be supplied, but locality and/or GC performance
- may be better if they are. Meaningless if :PURIFY is NIL. See PURIFY.
-
- :ENVIRONMENT-NAME
- This is also passed to PURIFY when :PURIFY is T. (rarely used)"
+ The save/load process changes the values of some global variables:
+ *STANDARD-OUTPUT*, *DEBUG-IO*, etc.
+ Everything related to open streams is necessarily changed, since
+ the OS won't let us preserve a stream across save and load.
+ *DEFAULT-PATHNAME-DEFAULTS*
+ This is reinitialized to reflect the working directory where the
+ saved core is loaded."
