I would suspect this patch from Kenny / Mistachkin (applied by me):
2004-07-20 Jeff Hobbs <[EMAIL PROTECTED]>
* generic/tclEvent.c: Correct threaded obj allocator to
* generic/tclInt.h: fully cleanup on exit and allow for
* generic/tclThreadAlloc.c: reinitialization. [Bug #736426]
* unix/tclUnixThrd.c: (mistachkin, kenny)
* win/tclWinThrd.c:
and this other looks possible:
2004-05-05 David Gravereaux <[EMAIL PROTECTED]>
* generic/tclInt.h:
* generic/tclThread.c:
* generic/tclEvent.c:
* unix/tclUnixThrd.c:
* win/tclWinThrd.c: Provisions made so masterLock, initLock,
allocLock and joinLock mutexes can be recovered during
Tcl_Finalize.
