Overly aggressive CFS

We're looking at CPU bandwidth control via CFS:

• https://www.kernel.org/doc/Documentation/scheduler/sched-bwc.txt

Reproduction program

Program does number of iterations, in each iteration we burn CPU in small chunks until we get 5ms of real time spent. On each iteration we also print how much

I recently came across the need to spawn multiple threads, each of which needs to write to the same file. Since the file will experience contention from multiple resources, we need to guarantee thread-safety.

NOTE: The following examples work with Python 3.x. To execute the following programs using Python 2.7, please replace threading.get_ident() with thread.get_ident(). As a result, you would need to import thread and not threading.

1. (The following example will take a very long time). It will create 200 threads, each of which will wait until a global lock is available for acquisition.

# threading_lock.py
import threading

Installing Graphite:

Graphite does two things:

1. Store numeric time-series data
2. Render graphs of this data on demand

What Graphite does not do is collect data for you, however there are some tools out there that know
