Hi, Felix.

Would you be willing to accept a patch to modify this?  I think it is
far more useful to have the profiler add new information to the
existing file (instead of overwriting it).

I decided to take some time and create a patch implementing this.  See
the file attached.  Basically, I do the following:

- Open the PROFILE file in append mode (so I won't overwrite previous

- Modify chicken-profile.scm to be smart enough to merge information
  from multiple runs, using a hash table.

If a user wants the previous semantics, all he needs to do is rm
PROFILE before running his program (another option would be to add a
--profile-overwrite paramter to Chicken?  I would vote against is, at
it adds complexity to Chicken's interface without being too useful).
What do you think?

BTW, I haven't actually got around to testing my changes.  They could
be wrong (I'm on a very slow machine, where building Chicken can take
hours; I might try them latter).

Thank you!  You are an excellent free software maintainer!


Ps: The structure of sort-by-calls, sort-by-time and sort-by-avg is
very similar.  Would you want me to capture it in a procedure and
mayhaps simplify things a bit?  Heh, I'm a bit of a perfectionist,
