Many years ago, Autoconf produced configure scripts that used 'sed'
for the job of replacing the various @FOO@ occurrences in *.in files.
When they switched to 'awk', it was for speed reasons, IIRC.

'sleep' is used by the Automake macros: In any configure script generated
with Autoconf + Automake, you find:

  sleep $am_try_res
  sleep $am_try_res
        sleep $am_try_res
  sleep "$am_cv_filesystem_timestamp_resolution"

I don't think it's worth making a distinction here between Autoconf and
"Autoconf + Automake", since most packages that use Autoconf also use
Automake.
