> JniBasedUnixGroupsMapping has some issues.
> * sometimes on error paths variables are freed prior to being initialized
> * re-allocate buffers less frequently (can reuse the same buffer for multiple
> calls to getgrnam)
> * allow non-reentrant functions to be used, to work around client bugs
> * don't throw IOException from JNI functions if the JNI functions do not
> declare this checked exception.
> * don't bail out if only one group name among all the ones associated with a
> user can't be looked up.
