*	Work around a linux libc bug causing a crash in TaskPool	Pavel Labath	2016-04-15	1	-2/+3
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Summary: Doing a pthread_detach while the thread is exiting can cause crashes or other mischief, so we make sure the thread stays around long enough. The performance impact of the added synchronization should be minimal, as the parent thread is already holding a mutex, so I am just making sure it holds it for a little while longer. It's possible the new thread will block on this mutex immediately after startup, but it should be unblocked really quickly and some blocking is unavoidable if we actually want to have this synchronization.

*	Add a new task pool class to LLDB	Tamas Berghammer	2015-10-20	1	-0/+88
	The purpose of the class is to make it easy to execute tasks in parallel Basic design goals: * Have a very lightweight and easy to use interface where a list of lambdas can be executed in parallel * Use a global thread pool to limit the number of threads used (std::async don't do it on Linux) and to eliminate the thread creation overhead * Destroy the thread currently not in use to avoid the confusion caused by them during debugging LLDB Possible future improvements: * Possibility to cancel already added, but not yet started tasks * Parallel for_each implementation * Optimizations in the thread creation destroyation code Differential revision: http://reviews.llvm.org/D13727 llvm-svn: 250820
