Multiprocessing and niceness value

Does anyone know of an easy way to set the niceness value of a Proc开发者_如何学JAVAess or Pool when it is created in multiprocessing?

os.nice(increment)
Add increment to the process’s “niceness”. Return the new niceness. Availability: Unix.

From http://docs.python.org/library/os.html#os.nice.

Is there a reason you can't call this in the child process?

Try importing the ctypes module and looking for pthread_schedparam() or SetThreadPriority() (Linux / Windows).
