Tried guile 2.0.9, tinyScheme, chibi-scheme and lua 5.2.
On MacOSX 10.8.5 memory footprint of default interpreter is:
guile 12.4 MB,
tinyScheme 984 KB,
chibi-scheme 2.7 MB,
lua 760 KB.
Executing 'hello world' with 'time' takes:
time guile -c '(display "hello, world!\n")' --- real 0m0.027s
time ./scheme -c '(display "hello, world!\n")' --- real 0m0.007s
time ./chibi-scheme -e '(display "hello, world!\n")' --- real 0m0.046s
time lua -e 'print("hello, world!\n")' --- real 0m0.004s
To sum up, for config files tiny-scheme or lua are perfect. Taking into account that lua is a full-featured language while tiny-scheme is a shrinked down one, lua is a clear winner.

Multithreading in FLTK
The very smart way:
http://www.fltk.org/doc-1.3/advanced.html
int main() { Fl::lock(); /* run thread */ while (Fl::wait() > 0) { if (Fl::thread_message()) { /* process your data */ } } } ////////////// void *msg; // "msg" is a pointer to your message Fl::awake(msg); // send "msg" to main thread ////////////// void do_something(void *userdata) { // running with the main thread } // running in another thread void *data; // "data" is a pointer to your user data Fl::awake(do_something, data); // call something in main thread
