Yes.  There actually seem to be two issues here.  The first one was a  
bug in the
suspend code.  I thought I fixed it in revision  
a11039205cd784fdf22acc63e69a0fee073e216e and posted an email about it  
on the 27th of August.

And I thought the monotone.ca server had been updated because I saw  
the problem disappear a little while after I committed the fix, but  
it seems to be showing the problem again.

The next issue is that there seems to be a lot of data transfer to  
decide that there
is nothing to transfer.  e.g. if I do two syncs in a row of  
"net.venge.monotone*" then
the second one was sending and receiving almost a megabyte of data  
for 0 updated revisions.  At the moment I can't double check this one  
as I'm resending the 233 revisions in suspended branches every time.

Be well,

Will         :-}
