Isn't it that slow because the *entire* ELF is read into memory?

So how should it work in your opinion?  I think it should not cache
everything at startup.  It should look for "ls.mod" when you run
"ls".  If it can not be found it should try all modules until "ls" was
found.  The cache is filled automatically.

Or use another autoloader if I understand things correctly.
