Yeah you really can't do two operations on the same sandbox at the same 
time... no locking...

edit is particularly bad as it uses temp files (CVS/Notify) to store its 
data, so anything that sees that thinks there's an aborted edit 
operation and tries to complete it, resulting in a mess.  Rewriting edit 
to remove that file is one of those things I've got on my priority list.

Client side locking isn't something I've really thought about as cvs has 
never had it and nobody has complained until today :)  Definately 
something to think about in the 2.6 timeframe (need to start writing 
these down somwhere as there are lot of them).
