[Haizea] Haizea crashing on canceling the lease

Looks like this was a bug in the code. Haizea wasn't cleaning up
correctly after the cancellation, so the scheduler thought it still
had to process the premature end (which, by the time the scheduler
wakes up, was in the past, which made it crash).

Anyway, I just committed a fix to SVN:

https://phoenixforge.cs.uchicago.edu/repositories/revision/haizea/686

I am preparing a new release (which should be out sometime next week)
so, if this isn't urgent, you can wait for the new release, which will
include the fix. Otherwise, it shouldn't be hard to patch the code
using the following diff:

Thanks for reporting this!

Cheers,
