Huh? Maybe I'm overlooking sth. but in L4Env we have locks and semaphores
- pkg/lock resp. pkg/semaphore. From my experience, these do their work.
The client library of the DOpE GUI also has a simple wrapping layer in
pkg/dope/lib/dope/include/sync.h and pkg/dope/lib/dope/{l4,linux}/sync.c.

If you were aware of the locking libraries just ignore this email ;)
