[Swift-devel] duplicated job submission in swift-0.92?

Uhhhh - I dunno.  I though Justin was going to merge changes from the stable branch (made after it branched) back to trunk on an as-needed basis, as a first step towards working towards 0.93 in trunk.

That seemed a reasonable approach. The reverse is harder to understand if thats whats been happening.

I know Justin's been doing some merging. Best to wait till he can explain what he's been doing.
