How much effort would it take to optimize a /bin/sh?
Would replacing uses of fork+execve posix_spawn be fast and
portable enough?
Even on Linux, performance sucks for me. I've been hoping dash
can use posix_spawn (or using vfork directly) to see if that can
help things.
That won't help with subshells, though...
