[MacPerl-WebCGI] Two questions concerning MacPerl

[Ricky Morse <rem14@cornell.edu>]

Hi!  I'm kinda new to programming in Perl, however I've managed to create 
the cgi I'm working on.  It's rather complicated, as it involves dealing 
with a lot of files, and is used for online signing of forms.  I have a 
few questions, however, that stand in the way of completing this CGI:

1) How does MacPerl handle multiple acgi requests at one time?  ie -- do 
I need to lock the files that I'm working with?  or can I be guarenteed 
that only one instance of the script will be running at once?  and should 
I lock the files anyways?

2) MacPerl keeps on crashing with error type 12s -- does anyone know what 
is causing this?  According to the error guide, and error type 12 is an 
"Unimplemented Core Routine" -- this is the error that debuggers trap, 
and usually indicates that a breakpoint was left in the source code... is 
this correct?  If so, how do I correct it, if not, what do I do -- this 
is a _major_ problem, as the script seems to crash MacPerl about once a 
day -- and we haven't even really started testing.  Further, when MacPerl 
goes down, you can't quit the .acgi (clicking on the quit now button does 
nothing), you can't relaunch the script, and the machine is left in a 
_very_ unstable state.  If you try to restart, as it is quiting 
applications, it freezes -- no mouse movement allowed.

Thanks muchly,
Ricky Morse
