[phobos] Suggestions for std.process

[Sean Kelly]

In *nix you can set a signal handler to be notified when a child process completes.  But the restrictions on what can be done inside a signal handler are such that maybe executing a callback from inside one isn't a good idea anyway.

Assuming that improving it currently isn't at the top of the to-do list for Phobos, I decided not to wait, and rather to write my own version.  If you want you can check it out here:
