Issue 52: crash when running 'regenerate_rosters' on NetBSD src and pkgsrc repositories.

I trigger graph.cc:72: invariant 'I(!next.empty())' violated

When attempting to migrate the NetBSD src and pkgsrc repositories 
from 0.28/0.29 to 0.30.  The crash happens shortly after starting 
the regenerate_rosters step.

The same crash can be triggered trying to cvs_import the same 
repository using a fresh 0.30 database.  I'm currently testing to 
see whether it is also triggered via netsync pulling from 0.29 into 
an empty 0.30 db.

the dump for the regenerate_rosters case ends:

also reproducible with mainline head 7b435ce7 on linux.

netsync test is still running

Comment 2 by Unknown User, Sep 20, 2006

Netsync test is *still* running.  I suppose its good that it hasn't 
crashed yet, but it's not going to be much of a workaround if it's 
this slow (and for all I know the problem is still there waiting to 
bite, it's just that netsync processes revs in a different order to 
the other things which fail quickly).

After 15.5 hours of pegging the pull-side cpu:

mtn: bytes in | bytes out |       revs in | revs out
mtn:  156.2 M |       152 |  30294/182256 |      0/0
