I suspect something is wrong with your load average reporting, you
are mis-interpreting what you are seeing, or you are really not
blocking as much as you think you are.
A process which is blocking on all threads should consume no CPU and
be swapped out. Block timeouts (eg poll()) will keep a process from
being entirely swapped out, but should still not hit system load
more than a nibble.
Something else is going on.
