+ ** bug fix: one less memory fault in INTERRUPT-THREAD, again
+ ** bug fix: gc and INTERRUPT-THREAD don't hang when the RT signal
+ queue is full
+ ** bug fix: finished threads are gc'ed properly
+ * fixed some bugs revealed by Paul Dietz' test suite:
+ ** CALL-NEXT-METHOD signals an error (in safe code) when the call
+ has arguments with a different set of applicable methods from
+ the orignal arguments.
+ ** The type error thrown by MAP now has a correct expected-type
+ cell.
+ ** DISASSEMBLE now throws a TYPE-ERROR when its argument does not
+ name a compiled function.
+ ** Three MISC tests where a large bignum was improperly coerced to
+ a float that couldn't represent that bignum during type
+ derivation were fixed.
+ ** SUBTYPEP can now handle types involving the negation of a
+ list-form FUNCTION type.
+ ** SUBTYPEP also now handles certain COMPLEX type specifiers such
+ as (COMPLEX (AND RATIO (NOT FIXNUM))).
+ ** READ-BYTE and WRITE-BYTE no longer take stream designators.
