When does this happen? Thread suspended in critical section

Question

I'm just wondering if the thread is in a critical section, can it be unloaded?

• Topic A : Enter CR
• Topic A : Pause
• Thread B : wants to enter CR, but cannot, because Thread A has a lock

If Thread A is unloaded, and therefore the mutex lock is stuck with Thread A , what can be done about this?
