Re: changes in 'require'

[Roberto Ierusalimschy <roberto@...>]

Now I have some numbers:

- time to load a quite small Lua file (4 one-line functions): ~100us
- time to load an already loaded file: < 1us
- time to search a non-existent file: ~30us

So, it does have an impact (mainly because, with the obvious
implementation, you have to pay it even when requiring an already loaded
module).
