I check that it is set by running "ulimit -s" without a numerical argument.
The reported value is the one I have set, viz. much larger than the default of
8192 (kbytes).  This is the soft limit.  The hard limit is reported to be
"unlimited".

If it matters, let me add that I'm running Python from within zsh.
 % zsh --version
zsh 4.0.4 (i686-pc-linux-gnu)
