Hi Rushabh
I am about to post a new patch set that fixes the deadlock problem,
but in the meantime here is a rebase of those two patches (numbers
changed to 0006 + 0007). In the next version I think I should
probably remove that 'stripe' concept. The idea was to spread
temporary files over the available temporary tablespaces, but it's a
terrible API, since you have to promise to use the same stripe number
when opening the same name later... Maybe I should use a hash of the
name for that instead. Thoughts?
