The crash is gone, as is some of the popping (at least during the first several
tests).  Unfortunately Unreal still crashes during the intro (unless I was
using the wrong binary, which is entirely possible since I didn't install the
compiled binary from the git tree, but rather tried running it directly from
the tree).  But let's get the test working first.

But there's still a bit of popping.  I've attached the most recent log.  The
popping starts after several of the "half second" delays (which go for much
longer, and then fail the test), on the CALLBACK_EVENT|WAVE_FORMAT_DIRECT run
with ten headers and zero loops.  A couple of the other runs have the same
behavior still.  But it is a lot better.  :-)

(Device 0 and 1 are the same.  Device 2 produces no sound at all, but that's
unsurprising since it's the IEC device and I only use analog stereo sound. 
Device 3 is the mapper; I killed the test partway through that one.)

I'll look into upgrading alsa as well, but that will have to be tomorrow (or
later).
