You're right. I checked and it seems like the job is finished, I can see that 
Vim got all the job's output. That's however what I see at the end of the log 
(the first line is the last line of the grep process):

/home/ramele/linux-4.6-rc5/block/blk-mq-sysfs.c:457:    blk_mq_enable_h [01m

It seems that Vim hangs in an infinite loop here. For some reason I didn't see 
it in the previous log, not sure why (maybe it's related to some changes I made 
to simplify the debug).

I hope that helps you. Let me know if you want me to chack further.

Thanks,
Ramel
