I only care about nsthreadtest in order to debug the Naviserver code.
Now nsthreadtest is working on all the combinations of platform and
versionf of Tcl I tried, great.

Unfortunately, nsd itself has some problems.

In my very limited testing, nsd linked with Tcl 8.5 appears to run
mostly ok on both Linux and Windows.  However, at least on Windows, it
has buggy behavior - ns_cond silently does nothing.  I have no idea
why.  I haven't tested yet whether Linux has the same problem.

Linked with Tcl 8.4, nsd immediately crashes on startup, on both Linux
(backtrace below) and Windows.  This surprises me...  Any ideas?  Does
this suggest some sort of incorrect linking in my build, or a bug
somewhere in the Naviserver code?

Has anybody actually been using Tcl 8.4 with Naviserver lately?
Staring it up with "nsd -c" threw a whole bunch Tcl errors because the
"namespace ensemble" command only exists in Tcl 8.5, not 8.4.  I fixed
that here:
