It could actually be that it is not too consistent, but it definitly
needs to compile against both: basically libwebsh.so (or websh.dll)
are compiled against the stub library, as it is loaded into either a
tclsh or websh or mod_websh, where a tcl library is already
loaded. mod_websh.so however must link directly to tcl.lib, as there
is no Tcl anywhere else in the application. So mod_websh.so must
properly know how to load Tcl.

Mhh. That's true. My impression was that if we need threads, we just
need to link against a threaded Tcl. I just added /DTCL_THREADS=1 to
the Makefile, but it doesn't seem to make a difference at least
concerning the reported instability of the test suite. (That doesn't
impley that it shouldn't be tehre, though ;-)
Unfortunately, I'm really bad with Windows debugging. If you have a
chance to look into this that would be wonderful. (nmake apachetest
for me just sometimes does not run through w/o error with Tcl85 or
Tcl86 on Apache2 and Apache 2.2) It helps if I sleep between calls to
the server and give it more time to start and shutdown, but I'm not
sure if that's actually the cause of the problem or if it's just a
latent timing problem that arises more often when requesting
earlier...)
