I think I've finally "tracked it down".  Or at least I've found
a workaround: if I pass "--disable-o_direct" to configure, everything
works fine.

While trying to track it down, I saw that calls to "read" (from within
_io in dev-io.c) would often return garbage (tho not always).  Not sure
if it's a problem in LVM2, or in uClibc, or in the kernel, but I think
I've already wasted more than enough time on this, so I'll just use
the --disable-o_direct workaround.
