added a nasty lock testing program
it opens 2 connections to each of 2 servers, and opens 2 fnums on the same file on each connection (a total of 8 file descriptors) then it does random lock/unlock/reopen requests in a 100 byte range on the file and compares the results from the 2 servers. strangely enough, NT fails this test against itself right now - I'm still trying to figure that out. (This used to be commit 2f14d7c9bca5e170b8d2c169801cb200021fd467)
