[MacPerl-WebCGI] Multitasking?

["Stephen Criddle" <stephen.criddle@saga.co.uk>]

I'm in the midst of redesigining our intranet site.  It runs Macperl and
Webstar 4.2.  I have a couple of questions about MacPerl and
multitasking, which will influence the way I write some of the core
modules.

Does MacPerl run more than one script at the same time?

Does MacPerl run more than one instance of the same script at the same
time?

I ask these two questions because if the answer is no to both, it makes
life a lot easier when it comes to record locking and so on.

To explain (in case my questions are a bit vague), imagine you have
three users who request SCRIPT A, SCRIPT B and SCRIPT A at almost the
same time (but the requests come in in that order).  Does MacPerl go:

Time ------>

SCRIPT A
        SCRIPT B
                SCRIPT A

or:

SCRIPT A
SCRIPT B
SCRIPT A

or:

SCRIPT A
SCRIPT B
        SCRIPT A

(I think that explains what I'm trying to ask...)
