Ok - discussed this with Andrew last night. It seems that this is only
a problem on Solaris. Solaris seems to have *serious* issues with fcntl
locks with multiple processes contending for locks. No other system we
run on seems to have this problem (they have their own problems :-).

Dave CB - can you investigate this within Sun please. This is a *critical*
part of Samba, we may have to look into a solaris-specific workaround and
this would be bad.
