No you dont have to lock memory when you write an extension. The GC scans
the C stack and call gc_mark on each SCM objet which is in it. The only thing
you have to do is to write a C function which call gc_mark on each component
of your structure which is of type SCM.

Everything should be more clear with a true documention on this subject (it
will be in the 2.2 release)
