we see host crashes because of large posts to pool-masters that are
due to this. The fix reduces the size of these posts. When we device a
more elegant solution I am all for it but at the moment the fix is the
most sensible protection against those crashes.
the way this causes crashes is because information is added to the
post on all vcpus
even those that are not actually allocated.
@Joris, please correct me, because I am wrong
