I'll accept your vote for those. There's a very good chance I'll do them.
I figured that if you are waiting for a task to finish, it's probably
because you are waiting for some variable to be set, and you could
check the variable.

The initial API is the minimum that I thought was needed.
It would be easy to add other calls, but I wanted to see what
people would ask for before I started adding stuff that might be 
rarely used or unnecessary.
