This is actually a scalability problem I've found now.
I've gone even futher on this.  

  *) winbind cache time now defaults to 5 minutes
  *) we no longer force an update of the sequence
     number when we have to query the DC
  *) we store the sequence number and timestamp in
     the cache tdb so that it can be shared between
     the parent and child winbindd process (in case of 
     running in dual mode)

Give it a try and see what you think.  I'm checking it into SAMBA_3_0
cvs as soon as the compile finishes.

cheers, jerry
