This seemed to work quite well -- the one real downside to the current GCD API is that it required a moderate amount of book-keeping in the consumer to handle suspending dispatch sources.  
Do we need some APIs like putting a set of sources in a group, and then can suspend/resume them all?

Also libdispatch will not remove/disable a kevent associating with suspending sources, implementing that feature may incur some overhead(Since we need check all sources associating with a kevent).
