I would appreciate any comments from the janitors list. This is one (of
many) cases where I made a decision about replacing

set_current_state(TASK_INTERRUPTIBLE);
schedule_timeout(some_time);

with

msleep(jiffies_to_msecs(some_time));

msleep() is not exactly the same as the previous code, but I only did
this replacement where I thought long delays were *desired*. If this is
not the case here, then just disregard this patch. 

Thanks,
Nish



Applys-to: 2.6.7

Description: Use schedule_timeout() instead of msleep() to guarantee the
task delays the desired time.
