Re: swapcontest usage in syncio.c

[Anand Avati <anand.avati@xxxxxxxxx>]

The change should be sufficient only in syncop_switchto(). Change in syncop_yeild() should not be necessary. I still don't understand how/why this change will help NetBSD, but it shouldn't break anything on Linux (calling makecontext() within or outside syncop_switchto() should not matter).

Is the attached patch resonable enough to be posted in gerrit?
