[Lots. Ok, I know that doesn't help. =]
The thing is, it happens occasionally. The more statements you throw at it,
the more likely it is to hang before completing the file...
As an attempt at quantification, I'll say this. We are currently using a
test file with about 5000 pairs of create/drop. It (almost?) never makes it
through a pass of this file. Your mileage may vary.

Absolutely. Certainly possible to imagine some form of race condition in
cygipc being responsible, but I'm only guessing from the symptoms (not from
any knowledge of the implementation of either postgres or cygwin/ipc).
