Jesper, sorry for the slow response on this one.

I've checked this in.

I have a guess on this.  mlprof uses Process.callWithIn, which in turn
uses fork/execp.  If . is not your path, then the execp will fail.  I
guess mlprof should use exec instead of execp.

I've checked in a fix for this.  I introduced some bugs when I was
doing the TextIO.inputLine changeover.

Sadly no.  The only thing I do is a "make" in doc/examples/profiling.
That exercises lots of stuff.
