The last bug I knew of (Linux fileserver hangs with new-style Linux 
threads) was the one we were suggesting LD_ASSUME_KERNEL 2.4.0 for. The 
1.2.13/1.3.74 changes seem to have addressed it (caveat; I did not test 
for that particular bug exhaustively at the time). Other than that, no 
issues known to me. The old-style Linux threads had been seen to have the 
issue that a single thread's cloned pid could die and leave the fileserver 
otherwise running but unhappy. All cases I knew of where this actually 
happened were triggered by other bugs.
