I've not seen this on MySQL but under Informix 7.24 on Solaris 2.6 I noticed a similar problem when doing a lot of number crunching and transaction logging was turned on. If you are running with transaction logging switched on then you might want to try turning it off. For some reason the database seems to get backed up writing to the log and this stalls everything else on the system, iowait figures go sky-high and I can only stop the process by doing 'kill -9 <pid>.
