Thanks.

Reading LockFileManager::readLockFile I noticed the stat+open sequence in

  error_code EC = sys::fs::status(LockFileName, Status, /*FollowLink=*/false);
...
 if (MemoryBuffer::getFile(LockFileName, MB)) {

This is normally an antipattern. The operation should just be tried
and any errors handled. The link can go invalid between the status and
the open, so the error handling following getFile has to handle it
already, no?

I patched your patch to just try to open. Let me know what you think.

Cheers,
Rafael
