If you want to open the handle for writing you need to add the "w" mode
f = os.fdopen(tup[0], "w") f.write("foo") You forgot to specify the open mode ('w') in fdopen() .
You can use
os.write(tup[0], "foo\n")
to write to the handle.

With out resorting to native code I don't think this will be possible .
Java has no way of accessing the processes for the other applications .
I don't think this is possible using AWT.

It works for most of the major operating systems ( darn near anything modern ) and is very easy to work with .
I think the best method out there is to implement the SIGAR API by Hyperic .

If not, is there a way I can guarantee thread safety by programming a certain way?
To clarify, when talking about "threadsafe,' I mean Python threads, not OS-level threads.

However, once control is passed out to a C extension another thread can be active within the interpreter .

To deal with your example, there needs to be some sort of 'tie-breaking' algorithm.... .
The priority is probably a hint to the JRE on how to schedule CPU time each thread .
Since we're talking about threads, I think that this never reaches the OS directly .
