Hi Daniel: Support for DISPATCH_SOURCE_TYPE_READ should be there. If I remember correctly its just support for processes and VM memory pressure that isn't available.

It would ideally need the underlying kqueue library to have EVFILT_PROC support, which it doesn't today.

In particular, I’m interested in the status of DISPATCH_SOURCE_TYPE_READ and DISPATCH_SOURCE_TYPE_PROC. Right now, NSTask is using Good Ol’ CFRunLoops for it’s event handling, and I’d really like to move that over to GCD as soon as I can.

I can’t say if anyone else on this list is working on this right now, but if not and if you’re really interested in finishing NSFileHandle, I would (very happily!) take care of the relevant implementation in NSTask.

I would like to fix the hangs issue in order to revert [3aa8434][0](disable NSTask tests for now since it can cause hangs., 2016-01-21), but want to avoid duplicating work. Fixing this should also resolve [SR-625][1]. Thanks.
