Description
Due to some call to usleep with low value, suricata causes an important load on some virtual system.
The attached patch fixes the issue but should have some severe implication on performance. Thus it only indicate where to look at.

Eric,
When does this occur? Any specific situation ?
What is your VM setup ? (mem,cpu,os).
Thanks
Peter,
The problem can be reproduced on a VirtualBox system (Host is a debian sid).
This is linked with a usleep(10) call in the flow manager. I've proposed a patch to Victor and Anoop which are currently reviewing it. The patch is attached to this comment.
has the current master fixed this issue?
Current master does not show the issue on my VM.
