[9fans] Quick question on stopping a process that waits for IO

[Roman Shaposhnik]

Guys,

when somebody tries to stop a process that is waiting for the IO the  
process
doesn't get transferred to a Stopped state immediately but only when
the scheduler sees it for the first time. This leads to a process  
writing to
a /proc/n/ctl being put in a Stopwait state which is a bit inconvenient.
Is there any way I can poke the target process so that it gets attention
from the scheduler an can be put in a Stopped state?

Thanks,
Roman.
