Clarifications: CVS Import Bug - Please Respond

[Oproescu Bogdan (KTXA 3)]

   Hi Derek and all, 

   So, which one is the problem here: is it that RCS-style locks 
   don't work correctly on their NFS-mounted file systems, or is it 
   simply that the source code of CVS is incorrect and omits File 
   and Directory locking prior to cvs imports? You described a fix
   for the second issue when CVS source code is incorrect, but if 
   this was also the case how would we make RCS locks work on NFS? 

   Cheers & Regards, Bogdan

I just waded through the code and can barely believe it myself.  I had
only meant to glance through to refresh my memory...

Perhaps no one has reported this before because the RCS locks have been
saving people in general.  This particular combination of an NFS mounted
repo and heavily used imports may be rare.
