I'm not aware of any memory leaks in TBNL and it's hard to say if
you're doing something wrong without seeing your functions.  As a
simple test I'd suggest running the same example with another Lisp
that is known to work with TBNL, like CMUCL.  What you're seeing
/might/ be related to SBCL's threading implementation.  I don't know,
I usually don't use SBCL.

Good luck,
Edi.
