Implementation itself is straightforward, but we need to add 3 impls of waiting
for semaphore with timeout.
POSIX have sem_timedwait(). Windows' WaitForMultipleObjectsEx() have timeout
arg. SysV have semtimedop().
That's what we need to add something like LWLockAcquireWithTimeout().
Does adding all these stuff sound like a good tradeoff for lock-safe
pg_stat_statements? If so - I'll start to implement this.
