<pre>Thankfully, this has been fixed by Chuck Silvers - ended up being a NetBSD-only
problem:
<a href="http://mail-index.netbsd.org/source-changes/2015/06/25/msg066995.html">http://mail-index.netbsd.org/source-changes/2015/06/25/msg066995.html</a>
fix Xorg coredumps that have started happening recently.
the problem is that we get a SIGALRM while we're sleeping during
a page fault on a mapping of a GEM object, and since we're sleeping
interruptibly, the GEM operation fails with EINTR. this error is
returned all the way back through uvm_fault() to the trap handler,
which responds to that error by delivering a SIGSEGV.
fix this by doing like the linux version of the GEM fault handler
and converting EINTR into success, which results in delivering the
original signal and retrying the fault.</pre>
