darwin: add another preemptive gui() call when using chg Changeset a89381e04c58 added this gui() call before background forks, and Google's extensions do background forks on essentially every invocation for logging purposes. The crash is reliably (though not 100%) reproducible without this change when running `HGPLAIN=1 chg status` in one of our repos. With this fix, I haven't been able to trigger the crash anymore.
