I don't have any hard numbers but the last time I played around with MinimalLock it was very
very slow. I view InterProcessLock as an intermediary between exclusive and minimal locking.

Are we talking about the variable name? In that case I would prefer a name
that makes it obvious what it is behind:

MutexLock

:-)

Did you actually do performance tests too? A mutex is rather expensive and
it should be avoided to acquire/release it multiple times unless really
necessary.
