New submission from Satrajit Ghosh:

multiprocessing cpucount returns the number of cpus on the system as returned by /proc/cpuinfo. 

this is true even on machines where linux kernel cgroups is being used to restrict cpu usage for a given process. this results in significant thread swithcing on systems with many cores. 

some ideas have been implemented in the following repos to handle cgroups:


it would be nice if multiprocessing was a little more intelligent and queried process characteristics.
