[libdispatch-dev] Why polling event sources with a kevent receiving queue of size 1?

Hi all,
I've noticed libdispatch will poll event sources with an one-entry kevent
receiving queue(queue_kevent.c:162, in function " _dispatch_mgr_invoke").
This will incurs more system calls and hence poorer performance. Why not
poll event sources with a larger kevent receiving queue?
