The above was very helpful and I now realize that the problem
most likely has to do with the very limited amount of memory I
have on the VPS I am using (128MB, no swap).  I get the 'cannot
start thread' error message when I try to start more than 3-4
threads.

Reducing maxthreads, minthreads to a smaller number gets around
the 'cannot start thread' error message but then I get a 'fork
failed - cannot allocate memory' message.  (This is actually a
common message I get on this resource starved VPS.)


I'm able to get the 2.0.3 web server or a minimally configured
Apache to start up fine even with mysqld (also minimally setup
with 8-10MB usage) running in the background whereas even with
mysqld turned off, trying to start the 2.1 webserver fails due
to insufficient memory.

This is what 'top' reports:

before I try to run spyceCmd.py -l -d, which seems to indicate that
even ~100MB free is not enough to start up the 2.1 web server... ?

Setting minthreads=maxthread=maxqueuesize=1 didn't help.
