The problems with releasing locks from threads has been fixed in the 2.1.xx
tree, but apparently hasn't been backported to 2.0.xx. If someone wants to work
on it, the changes are relatively minor -- the lock code was changed to use the
files_struct pointer as the "owner" value, and the close code for posix/flock
separated.
