FWIW, there has been a concerted effort in libtool-2.0 to replace 
fork/exec'ed subprocesses with builtins whenever available (e.g. 
fork/exec on ash, but if SHELL=bash/ksh/..., use some builtin 
construct).  This is bound to help with respect to configury-type 
"benchmarks" as projects upgrade their libtools.

Thus, things are only going to get better, in the ash-vs-bash race.

With respect to alternatives, I was thinking about packaging that up for 
cygwin anyway, because the new family of automake packages could use it, 
instead of the hacked-together pseudo-alternative scheme it's using now. 
  I haven't had a chance to look into it yet, tho.
