the code is inlined.
- [25-feb-1998] [libbasic/Object.st 1.223]
#perform: family of methods did not care for pending singleStepInterrupts.

Notice, that not all iso8859-1 characters are available in those fonts.
- [25-jun-1997] [libview/WSensor.st 1.103]
deadlock situation with interruptActions during eventQueue handling

- [27-feb-1997] [librun/new.c 1.249] idenitytHash clobbered in #become:
in certain situations, #become: did not exchange the hashKeys,
which lead to trouble with objects being held in a set or dictionary.

ST/X allocated more memory than required, if the fastMoreOld flag
was on and the compression limit already reached.
- [26-feb-1997] [stc/codeexpr.c 1.116] inline float multiplication
stc generated syntactically incorrect C-code for inlined float multiplications,

methodDictionary resized itself wrong when entries where removed
- [14-feb-1997] [stc/codeexpr.c 1.115] here-send in class methods
