I see - it is the AbsorbFsyncRequests() added in mdsync() loop and you want 
to avoid unecessary fsyncs. But the remove-recover method you use has a 
caveat: if any hash_search(HASH_ENTER) failed when you try to reinsert them 
into the pendingOpsTable, you have to raise the error to PANIC since we 
can't get back the missing fds any more.
