HH\Lib\File\Lock
A File Lock, which is unlocked as a disposable
To acquire one, call lock
on a Base object.
Note that in some cases, such as the non-blocking lock types, we may throw
an LockAcquisitionException instead of acquiring the lock. If this
is not desired behavior it should be guarded against.
