This is not necessarily 'nothing'. I don't know how bulk_mailer works
but if it runs as one process with internal threads (as opposed to
forking itself for each job) then a load average of 0.7 could mean
70% CPU usage if bulk_mailer is all that is running.
Load average is how many processes are ready to run. A runaway CPU
bound process on an other wise idle system will give a load average
of 1.0 but be consuming 100% of the CPU.
Corrections and comments welcome.
