- 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
