spawnv and stdout redirect

[Christian Maus]

I am trying to write a cgi-script in python which should spawn a new 
process and print a message to the user, stating that the process has been 
started.
Unfortunately, this script has to runon a windows machine and I have the 
problem that my script doesn't terminate because the process keeps writing 
to stdout. Is there a way to redirect the stdout of this process to nul ?
Simply adding ">nul", "2>nul" to the spawnv arguments does not work.

Any help is appreciated.
