| Gaby, thanks, I'm using GCL but I'll try it with SBCL, I didn't think of

Here are some subjective opinions:
* debugging with GCL can be painful, especially in experimental phase.
* my debugging with SBCL is so far unparalleled by any other free Lisp
system I have been using.
* SBCL's support for shared library means that you don't need to
modify src/sockio-c.c while you're still in experimental mode.
You can edit your local C files at will, build the shared libary
and load it with loadNativeModule$System, e.g.
loadNativeModule("mylib.so")$System
then use the Spad FFI interface, without having to modify
interp/sys-os.boot
In summary, you will just need to know C and Spad. :-)
