easy way to reproduce (~25%?) is to create a self-referential file:

#!/usr/bin/env es
./a

related (?): seems to miss a Ctrl-C occasionally as well.

rc changelog suggests they rewrote signal handling code. Worth a look.

Actually, nothing to do with self-referential file. Even a Ctrl-C on a sleep 1 will cause this.

Why didn't I read the mailing list comment before doing that. Oops. Clearly some sort of race condition that I'm too slow (ha ha) to think about at the moment.
