It's not hard for the user, and less work e.g. when migrating from an
existing Bash script. I may have put in the effort to use a recursive
descent parser under the hood, but why should the user of the library
care? It doesn't make their life harder. And it's not complicated, not
even particularly complex - such parsers are commonplace.

By that token, disasters await if you ever use threads, unless you
know what you're doing (and sometimes even then). Sarge doesn't force
the use of threads with forking - you can do everything synchronously
if you want. The test suite does cover the particular case of thread
+fork. Do you have specific caveats, or is it just a "there be
dragons" sentiment? Sarge is still in alpha status; no doubt bugs will
surface, but unless a real show-stopper occurs, there's not much to be
gained by throwing up our hands.

BTW extproc is nice, but I wanted to push the envelope a little :-)
