Subject: set minimum darwin kernel rx sleep
X-Git-Tag: openafs-devel-1_5_72~3

set minimum darwin kernel rx sleep

never be willing to sleep less than 500ms. additional tweaks to the
rx scheduler may be needed however before we always slept for 500; now
we'll sleep longer if no events are pending (but not forever)
