"Spurious notifications" are mentioned on the page
"http://tcl.tk/man/tcl8.5/TclLib/Thread.htm#M7".
=> The following code in the function
"Tcl_FinalizeNotifier" (file
"http://cvs.sourceforge.net/viewcvs.py/tcl/tcl/unix/tclUnixNotfy.c?rev=1.20.2.1&view=markup")
should be improved.
"...
Tcl_ConditionWait(&notifierCV, &notifierMutex, NULL);
result = Tcl_JoinThread(notifierThread, &ignored);
..."

Please add the test for the predicate in a while loop.

    This is correct. I also noticed this bug while going after some
    other bug reported in Tk project.
    This should be solved BUT I'll refrain from this until
    the 8.4.11 goes out.
    I'm assigning this to myself now.

    This is now fixed in core-8-4-branch and head.
