My apologies about the last post; I posted my "test" code by mistake,
with hard-coded path information. Here's for future reference
something that is general and should work cross-platform.

def exec_external(code=None, path=None):
"""execute code in an external process
currently works under:
* Windows NT (tested)
* GNOME
* OS X
This also needs to be tested for KDE
and implemented some form of linux fallback (xterm?)
"""

path = os.path.join(os.path.expanduser("~"), "temp.py")

that
