OK, that sounds like it confirms my theory :).

Waiting is definitely not a good option. Imagine some user with a slower
PC suddenly experiencing the same problem because we didn't wait long
enough ;).
Could you try the attached patch? It should reload files multiple times
if they change in-between.
To apply patches in *nix run the following command from your
texworks-read-only directory:
patch -p0 < issue-426_reload-file-until-up-to-date.diff
and then rebuild Tw using make.

PS: I've opened a new issue on Google Code
(http://code.google.com/p/texworks/issues/detail?id=426), basically for
when the patch works.
