I'm not sure if something based on /dev/urandom will be accepted
upstream as /dev/urandom is not available everywhere.

This is only a half-bashism, on shells without special support for
$RANDOM the variable simply evaluates to the empty string.
This is just "hgeditor....$$", so it is easier to create name
collisions, but still no security risk as the script simply aborts
in this case.
I guess the ideal solution would be to rewrite hgeditor in python,
but if you can replace the creation of the temporary directory with
a simple call to
python -c "something"
it would be enough to solve your current problem.
