I have run the kernel build several times and this is always the
result.  I also had an rsync killed for out of swap.  The interesting
part is that at no time did I really run out of swap.  This is on an
original BeagleBone with 256M of ram and 768M of swap.  At no time did
pstat or top in another window report that all the swap was used.  In
fact swap use never got above 10%.

I have been using BSD since the early 1980's and have never seen a
system report a process being killed for out of swap when there is
still plenty of swap before now.

Ideas?
