there's a race acquiring mp3parse->pending_accurate_seeks_lock. It's acquired
from both the seeking thread and the streaming thread. The deadlock happens
when a seek happens; the lock is taken; in the meantime the streaming thread
tries to acquire it too but it's taken so the streaming thread blocks; basesrc
flushes and waits for the streaming thread to stop -> BOOM
