the mailing lists.

I've been having problems for quite a while now with frequent lfs
deadlocks.  As of -current of ~one day ago, I built a kernel (i386)
and got two deadlocks while using LFS within a few hours of each
other.  After I applied the LFS part of the patch I sent in for this
problem about two months ago, I've yet to have another deadlock.
*fingers crossed*

Does anyone have any comments on whether or not this patch should be applied:
