Same here, so out of curiosity i ran strace -efile -o log vim, and
edited a few files. I observed vim looking for a directory called
$TMPDIR in the wd, and using it as you would expect. Obviously a bug,
and perhaps some minor security implications, anyone want to
investigate? :-)

(e.g. enter :let foo=system("/bin/ls"))

Thanks, Tavis.
