Serious performance issues with 1.9.0

[Martin Ward]

Running a test program on Guile 1.8.7 takes 100 seconds CPU time.
On Guile 1.9.0 (beta) the same program takes 237 seconds CPU time!

For comparison:

Gambit v4.4.4 takes 60 seconds.
SCM version 5e5 takes 20.7 seconds.
Hobbit compiled code running under SCM takes 1.1 seconds!

There was some talk a few years ago about integrating the Hobbit
compiler with Guile: but nothing seems to have come of it.

I can send you the code if you like (its the FermaT Transformation System
which is released under the GPL) its about 7.7MB of Scheme source,
so I didn't want to include it in this message :-)
