The problem is advisory file locking. I'll try to debug
it later, but something changed in how
fcntl(fd, F_SETLK,{...,F_WRLCK,...}) works. It return an
error now. Or maybe d4x just fails to unlock it, it doesn't
check if unlock failed.
The program doesn't show the real value of errno, just
handles EINVAL and ENOLCK, so exact analisys is not possible
apart something bad happened ("is already opened").
The EINTR case, for instance, would cause similar behaviour.

I suppose d4x just incorrectly uses it, but cannot say anything
for sure.
