If # of execs is that critical, it probably should not be in bash anyway. OpenBSD (at least 3.1)'s bash appears to be in /usr/local/bin/bash, NOT /bin/bash. I'd go with the /bin/env solution for now; it maximizes the "it just works" factor, and when it comes time for .in files much of the cogito code (at least) will probably be rewritten in Perl, and anything performance-sensitive will be in C.
