But I see only one real contention problem: When tons of
locks exist on the locking.tdb we might run into the
O(#oflocks) complexity on fcntl in the Kernel. Everything
else should in theory be relievable the hash chain length.
The kernel inefficiency is what I wanted to easy by having
multiple locking.tdb files, thus trading file descriptors
for locks per file.
But before measuring it this is all hand-waving.
