I have just committed a fix for a race condition in systrace.
Unfortunately, as a result of this, part of the interface between
the systrace binary and the kernel has changed.

So the systrace binary and kernel need to be in sync for systrace
to continue to work.  If not, you will most likely see an error
like the following when you try to use systrace:

	systrace: nbsd_replace: ioctl: Invalid argument

Should I bump the kernel version for this change?

Thanks
