Process p1 is currently being swapped in. | 2. Process p2 calls linux_ptrace(PTRACE_GETFPXREGS, p1_pid, ...) | 3. After acquiring a reference to FIRST_THREAD_IN_PROC(p1), | p2 blocks in faultin() while p1 finishes being swapped in. | This means p2 won't get back the lock on p1 until after p1's | threads are runnable. | 4. After p1 is swapped in, the first thread in p1 exits. | 5. p2 now uses its dangling reference to p1's first thread. Approved by: re (scottl)
