Dunno if it's a real hint (I still don't have a 7.3 distro available, yet), but:
1. In my previous experiences with interfaces/libpgtcl and pl/tcl I had to comment out the Tcl_CreateChannelHandler and Tcl_DeleteChannelHandler in pgtclId.c from interfaces/libpgtcl. And pgtcl.dll worked.
2. Actually pltcl.c didn't need this "patch", but as I've verified now, there are pltcl_[*]_handler functins that can rely on the two functions above, that are not (or are defective) present in libtcl.

The above problem was not due to exhausting the Cygwin heap. Instead,
it was cygipc's shmget() returning ENOMEM because /tmp/cygipc_0 was open
and mmap-ed in another backend:
(libcygipc) newseg : LBuff = /tmp/cygipc_0, errno = 13, return -ENOMEM (2)
See the following thread for the root cause analysis:
http://cygwin.com/ml/cygwin/2003-02/msg00255.html
I'm amazed that (so far) only PL/Tcl has triggered this problem.
Does anyone have any ideas on how to workaround this problem? Is it
time to switch to the Win32 version? :,)
Thanks,
Jason
