Cole Robinson 6869760732 asyncjob: Fix issues with multiple dialogs (bz 1003101) 
Basically, drop usage of nested main loops. As has been documented in
other commit messages, we use nested main loops in ways they aren't
supposed to be used. They gave us async behavior that would block
callers, but had weird behavior in some edge cases.

Switch to having async dialogs be 100% async, requiring the user to
pass in a completion callback which is triggered after the async
action is complete.
