Is there a way to single thread specific builds when the threads count is >1?

We have 100-ish builds, of which about 10 use the same database (DB,
user, schema) for junit tests.  

I would like to enable parallel builds within CruiseControl by setting
the <threads count='8' />, but I can't have any of these afore-mentioned
10 builds run concurrently with the others.

Is there a way to specify that these builds have to run single-threaded?

Also, while on the topic of increasing the thread count, has the issue
of having the log files getting the incorrect contents been resolved
yet?  I see it in 2.7.1, and I saw that it was noted to still be present
in 2.8.1.  If this is still an issue, is there a tracking number for it
that we can check to see if it is resolved in the future?

Thank you
