Basically, run two or more popens in parallell, and when there is data
on one of them read it and do some work.. 

Basically what I do now is do two popen2, do a wait on the first, chew
some data, wait for the second, not critical at the moment, just
interested what to do if I had to chew the data from the second
process first.

No problem at the moment :-) Only trying to sort out different methods
so I know how to handle a problem when it comes :-)

mmhm I had a problem associating pclose to pythin fileobject close.. I
was looking for pclose in the python docs :-)

You mean like popen2(["command", "param", "param"]...)?

Thanx for the help!
