Summary: fork()/execv() IDE Crash

Details: I'm just learning the fork()/execv() business and i'm sure this
code is crappy... but it does crash IDLE on Windows 98
#system test
import os
MyList = ['127.0.0.1']
while 1:
    
    os.execv('C:\Windows\ping', MyList )
    os.fork()

Comment:
Assigned to effbot for pondering.  On Win98SE, the loop isn't needed, and
neither is the fork.  os.execv is enough to crash IDLE.  It dies in
tk83.dll.  If I do

bin = r'\bin\wc.exe'
os.execv(bin, [bin, bin])

then wc does run to completion, so I imagine Tk is mondo confused about
Python going away.

"Nobody", fork doesn't even exist on Windows:

>>> import os
>>> os.fork
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
AttributeError: 'os' module has no attribute 'fork'
>>>

This is stuff is natural only on Unix systems.  On Windows, play with the
os.spawn* functions instead.
