Yappi should be able to measure CPU time also

[GoogleCodeExporter]

Yappi shows wall-clock time. It should have a mode for CPU time (to exclude 
IO-based delays from measurement)

Hacky environment-variable-based Linux patch for this:

Exactly, I already have a branch for this. You can check out the branch from 
bitbucket page. Branch name is native-perthread

What I want to accomplish is to have a way of getting thread times independent 
of the underlying OS. 

On Windows:
GetThreadTimes()

On Linux(since 2.6.0(2004)):
/proc/[your PID]/task/[thread ID]/stat
Reading proc value from Linux(instead of clock_gettime()) avoids the librt 
dependency during compile and seems more portable.

On MacOSX:
Someone implemented a sample here:

So, once these are all implemented and tested, we will have a accurate 
multithreaded profiler.
