Package libdispatch

Apple's Grand Central Dispatch library

Grand Central Dispatch (GCD or libdispatch) provides
comprehensive support for concurrent code execution on
multicore hardware.

libdispatch is currently available on all Darwin platforms.
This project aims to make a modern version of libdispatch
available on all other Swift platforms. To do this, we will
implement as much of the portable subset of the API as
possible, using the existing open source C implementation.

libdispatch on Darwin is a combination of logic in the xnu
kernel alongside the user-space Library. The kernel has the
most information available to balance workload across the
entire system. As a first step, however, we believe it is
useful to bring up the basic functionality of the library
using user-space pthread primitives on Linux. Eventually, a
Linux kernel module could be developed to support more
informed thread scheduling.
