Linux only returns -SIGBUS when:
- trying to swapout/swapin an invalid page
- no more real memory can be allocated, when the allocation
was already promised
You can try to work around this by making kswapd more
agressive (/proc/sys/vm/kswapd). Documentation for this
is in Documentation/sysctl/vm.txt...

Hmm, shouldn't be much of a problem, except maybe when the
working set grows _far_ too large for the Linux MM subsystem
to handle. OTOH, kswapd should get more agressive all by
itself... Maybe I should add some auto-tuning code to kswapd
(then you can watch the values in /proc/sys/vm/kswapd change :)
