So the problem I'm seing is that there's a typo/bug in
ReorderBufferSerializeTXN(). It closes the filehandle after each
individual spilled file instead of keeping it open for up to 16MB of
WAL. On linux that doesn't hurt particularly much, the file isn't
flushed to disk. Which presumably is why we haven't noticed. But if
windows does that differently...
