Thanks for the bug report. I see that the current Git version has evolved a 
bit, in that it now calls 'write' (which is async-signal-safe) rather than 
printf and fflush. However, it still calls gettext (which is not 
async-signal-safe) and it calls jump_to_top_level (which is even less so), so 
there's still a couple of bugs here.

Agreed that a flag-based approach is the way to go, though I expect your patch 
won't be quite enough.
