function to call and its argument
nthreads -- integer; number of threads to use
OUTPUT:
Executes the given list of commands, possibly in parallel,
using nthreads threads. Terminates setup.py with an exit code of 1
if an error occurs in any subcommand.
WARNING: commands are run roughly in order, but of course successive
commands may be run at the same time.
