Hi Akim,

I think autom4te should lock it's cache when it runs, to cope
with current runs of overlying tools.  

>From a (Makefile-)dependency point of view, autoconf and
automake can be run concurrently.  It would be easy to force
autoconf to run before automake (is this wanted?), but that
would just fix one instance of a more generic problem.  The
issue, from what I can say, is that autom4te is used by several
tools but isn't re-entrant.
