[Chicken-hackers] Stray diagnostic print in lolevel.scm

[Tony Sidaway]

I don't have commit access.  This is a minor gripe anyway.

I've been using object-evict and object-release. In calling the latter
I notice that I get a printed diagnostic trace in the form "release:
OBJECT" for each evicted object I release.

This is due to the expression '(printf "release: ~s~%" x)' in the
definition of object-release, in the darcs copy of lolevel.scm, at
release 2.519.

Eviction and release are recursive so releasing a complex object will
produce a lot of diagnostics on (current-ouput-port)!
