+## Modern and efficient C++ Thread Pool Library
 
 
 A thread pool is a programming pattern for parallel execution of jobs, http://en.wikipedia.org/wiki/Thread_pool_pattern.
@@ -10,7 +10,8 @@ More specifically, there are some threads dedicated to the pool and a container
 
 A thread pool is helpful when you want to minimize time of loading and destroying threads and when you want to limit the number of parallel jobs that run simultanuasly. For example, time consuming event handlers may be processed in a thread pool to make UI more responsive.

 - standard c++ language, tested to compile on MS Visual Studio 2013 (2012?), gcc 4.8.2 and mingw 4.8.1(with posix threads)
 - simple but effiecient solution, one header only, no need to compile a binary library
 - query the number of idle threads and resize the pool dynamically
