Hello-
I'm scripting a little thing to pick a random MAME
file and launch it (save me the hassle of choosing
one).
How can I do the equivalent to the python win32
startfile()? Does startfile work on BSD/Linux?
If I cannot use this, how can I say execute this command?

os.startfile() is only available in Windows.

It depends what your desktop environment is. If you run GNOME,
you can write it like this:
import os
def startfile(url):
os.system("gnome-open " + url) # quote if you can't trust user.

Also- I do not launch x-mame from the GUI, I use a
script (in Perl) to select and choose my game of
choice. So I suppose what I am looking for is
something that allows me to use a *nix system command
from within a Python script.

That's not a Python or Zope limit. It's a FreeBSD limit.
Use command 'limits' to show your settings.
Normally data size is set to 512M, increase this.
In /etc/login.conf are settings for limits,
some limits are set with sysctl and some are compiled into
the kernel.
Use man to get more info, I don't now the exact place yet.

If you just want to launch a command:
import os
os.system('unix shell command here')
If you need the stdin/stdout/stderr channels from the process you launched,
to communicate with it over stdio:
import os
stdin, stdout, stderr = os.popen3('unix shell command here')
# now you can do i.e. stdin.write('data going to program')
If you want the new process to replace your python process (exec):
import os
os.execvp(programname, (arg1, arg2, arg3, ...))
# os.execvp doesn't return - so you'll never reach this comment
If you want to start the process and wait around for its return value:
import os
returnval = os.spawnvp(os.P_WAIT, programname, (arg1, arg2, ...))
or if you want to start it and get its PID immediately:
import os
pid = os.spawnvp(os.P_NOWAIT, programname, (arg1, arg2, ...))
Thanks for using Python and FreeBSD!

this is a kernel limit.
i got around it like by recompiling the kernel with these lines in the
kernel conf file:
options MAXDSIZ=3D"(768*1024*1024)"
options MAXSSIZ=3D"(256*1024*1024)"
options DFLDSIZ=3D"(768*1024*1024)"
and then these lines in /boot/loader.conf:
kern.maxdsiz=3D"1610612736"
kern.dfldsiz=3D"1610612736"
kerm.maxssiz=3D"1610612736"
then a reboot.
and then putting unlimit in the zope start script (csh shell).
you should of course decide which numbers are best for you
