Sure, start by looking at the source. But also open a mantis issue in
category "VM", because IIRC there are C platform source changes involved
in addition to the Smalltalk, and you may want changes to the squeak start
script to pass the return value from the squeakvm executable back.
I recall doing a trivial implemention of this for the interpreter (which
is indeed trivial), but Eliot also added some platform support for reasons
that I can't recall at the moment (but maybe a search of vm-dev from that
time period will find it).
