I for one do not know the answer, and have not run across it. I did read that Seti may limit the work units to 100 for CPUs and 200 for GPUs so it may not be possible to bunker any more.
If you come across the answer give us a report.
Where is a way around the 100-wu-limit...
... since this relies on the info reported by the BOINC-client, and very old clients doesn't report the wu's...
... but, if not mistaken, this means pre-v4.45, since v4.45 supports the re-issue of "lost" wu, since this client sends info about all wu's on client...
It is a possibility the client relies on some other info added in a later client, but regardless of client it's atleast pre-GPU so...
Another possibility is to setup multiple virtual machines, since this is a different machine of course each machine is allowed 100 CPU-wu's. No idea how large the impact of running virtual machine is...
