OK, fine.
That's something important to know then.
If my website is made of hundreds of different pages, then, I should better
ensure that lexical variables are properly freed up.
Even if that's not good programming practive, at least, with global
variables, we are sure that the same memory locations are used across
different scripts. (which is not the case with lexical variables)
Thanks for all your help, I now have a clearer picture.
Lionel.

get access to the memory used by test2.pl is freeing up test1.pl lexical
variables, by undefining them?
Yes.
And what if I run test1.pl twice without undefining its lexical
variables?
Will the same memory space be used twice, or will each call use different
memory space (I'm talking here about situation where the same Perl
interpreter is running the script twice in a mod perl environment)?
It will reuse the already allocated memory. And the second pass is
faster because the memory is already allocated.
