   I mean "too many I/O operations"..


from my observations, this isn't the case.  when i've had softdep & rm
take *forever* on me (ie, the 'df' output takes minutes to actually stop),
i've run 'vmstat 1' and often the disks are completely idle for 10's of
seconds at time.


chuq has given me a test to run next time i'm seeing this, to drop to
ddb after the rm(1) completes and see how many pending softdeps there
are.  i think he may believe that there are far far too many.  that i've
had my kmem_map explode during one of these episodes tends to lead
credence to this idea...
