- we should probably extend pthread_mutexattr_t with a field to create a
single linked list of all instances. This requires changing the
pthread_mutexattr_* functions.
- a new attribute for mutexes: number of times we spin before calling
sys_futex
- for adaptive mutexes: when releasing, determine whether somebody spins.
If yes, for a short time release lock. If someone else locks no wakeup
syscall needed.
- test with threaded process terminating and semadj (?) being applied
only after all threads are gone
