Summary: A 'dogpile' lock, typically used as a component of a larger caching solution

Description:
A "dogpile" lock, one which allows a single thread to generate an expensive
resource while other threads use the "old" value, until the "new" value is
ready.

Dogpile is basically the locking code extracted from the Beaker package,
for simple and generic usage.
