ahh. right. ok. interesting. ok, well the purpose i have in mind
for it is actually _as_ a platform-independent web browser, without
having to have a whopping 30mb download of c/c++ and having to also
compile python bindings to whatever web engine...
basically i want access to W3C DOM functions (the ones that people
but enough about that - the idea of getting grailbrowser
up-and-running again i think people would find insane/amusing enough
to try to get it going again. searches for "grailbrowser" show loads
of people trying and failing to get it to work, so there is definitely
interest out there.

yes - i was disappointed about that when it happened: i had a project
which relied on it.
rexec, regardless of the "breakage", actually had other benefits,
most notably demonstrated by overloading import to allow scripts to be
loaded out of sql databases rather than off the filesystem, on-demand.
whether sandboxing was broken or not was completely irrelevant, as
far as the overriding / sub-classing of rexec was concerned.
by adding in that exception "go to hell in a handbasket!" right at
the beginning of the rexec module i basically had to either take a
copy of rexec.py and remove that one line (and then maintain that
copy, forever), or can the project.
