In std.parallelism, I have a simple need to block on all tasks in a pool being
completed.  (In my use case tasks don't return a value, and errors within a
task are discarded.)  Currently the only way to block would be to manually
maintain a collection of all tasks added to a pool.

I propose that TaskPool.finish() take a backwards-compatible option to block:

   finish(bool block=false)
