changes in sbcl-1.0.16 relative to 1.0.15:
* minor incompatible change: change PROBE-FILE back to returning
NIL whenever we can't get a truename, as was the case before 1.0.14.
+ * minor incompatible change: SB-BSD-SOCKETS:NAME-SERVICE-ERROR now
+ inherits from ERROR instead of just CONDITION.
* optimization: binding special variables now generates smaller code
on threaded platforms.
* optimization: MEMBER and ASSOC are over 50% faster for :TEST #'EQ
* optimization: modular arithmetic for a particular requested width
is implemented using a tagged representation unless a better
representation is available.
+ * bug fix: attempt to obtain *SCHEDULER-LOCK* recursively when
+ unscheduling timer at the same time as another timer fires.
+ * bug fix: don't reschedule timers for dead threads.
* bug fix: periodic polling was broken. (thanks to Espen S Johnsen)
* bug fix: copying output from RUN-PROGRAM to a stream signalled
bogus errors if select() was interrupted.
