Stop lock decorator from leaving tempdirs in tests
In some versions of python 2.7, we must use the nonlocal keyword to
give an inline function access to a variable in the enclosing scope.
This leads to a tempdir not beaing cleaned up because a boolean in
the synchronized decorator doesn't get set properly. Since we are
still supporting python 2.6, this patch removes the method call
completely so we don't have to worry about locality.
The patch also moves acquiring the lock inside the try, except to
make sure the tempdir is still cleaned even if there is some issue
with getting the lock.
Fixes bug 1047530
