Description

The new locking API currently only uses RuntimeException to hint at errors during lock acquisition.

While this already has the disadvantage of catching other @RuntimeException@s the issue becomes rather clear with the non-blocking example:

try {
  $result = $locker->acquire(LockingStrategyInterface::LOCK_CAPABILITY_SHARED | LockingStrategyInterface::LOCK_CAPABILITY_NOBLOCK);
catch (\RuntimeException $e) {
  if ($e->getCode() === 1428700748) {
    // some process owns the lock, let's do something else meanwhile
  }
}

This requires knowing about this special case and knowing the magic number here. A dedicated exception would make this clearer.
