This sounds great.  How does its performance compare with 'dash'?

Are the various issues described in the GNU Autoconf portability notes 
(http://www.gnu.org/savannah-checkouts/gnu/autoconf/manual/autoconf-2.69/html_node/Portable-Shell.html#Portable-Shell) 
avoided/fixed by this shell?  SunOS's stagnant /bin/sh has been a 
continuing issue with POSIX shell script portability.  As a result, 
Autoconf configure scripts typically elect to re-run themselves with 
bash (the World's Slowest Shell) on Solaris sytems.  If this shell is 
indeed good enough for Autoconf configure scripts, then it would be 
good to submit an Autoconf patch so that future configure scripts know 
how to detect and use it.
