[132fad6fde]. Fixed GetCache to use TclpSysAlloc+memset instead
of calloc. Now consistent with tclWinThrd.c which no longer
uses malloc in its TclpSysAlloc implementation.
Distinguish hanging from crashing in exit tests.
Remove ChannelHandlerEvent struct, which has never been used in all of
recorded Tcl history.
Still need to purge comments of mentions of ChannelHandlerEventProc()
which is similarly pre-historic.
[ccc2c2cc98]: lreplace edge case
Make corrections to long-false comments.
Remove unused macros.
Change one '#ifdef' to '#if defined()' for improved consistency within the file,
as in checkin [211aa43013].
Exceptional handling of oo::class has to be consistent throughout.
Refine TclFinalizeThreadData so that the quick-exit optimization really only affects exit.
[84af1192f5]: [regsub] compiler no longer confused by quantification handling.
[2486824] Improve error message; not all that upvars is an upvar.
[2486824] Improve error message; not all that upvars is an upvar.
[cee90e4e88] Correct error in stack depth checking.
Better pic flag for OpenBSD.
