Subject Re: @param seems to be shared between Execute calls

Note that, under Apache, the cleanup code happens at the end of each 
request - each of which could have dozens of Execute calls, between which 
it is very definitely NOT called.

I have not used Embperl much from within server scripts, but in my limited 
use there, I've never seen the cleanup code fire.  I suspect each script 
is considered 'a request' for the purposes of the cleanup code (well, as 
far as docs are concerned.  I don't know if the code actually fires on

@param seems to be shared between Execute calls


We're seeing an odd bug where @param seems to be shared between Execute 
calls in the same process. The following code is a test case for this:

#!/usr/bin/perl -w

use strict;
use Embperl;

my $output1;

my $input = '[- $param[0]->{hello} = 42; -]';

                 inputfile => "blah",
                 input => \$input,
                 output => \$output1,

my $output2;
my $input2 = '[- use Data::Dumper; print Dumper(\@param); -]';

                                 inputfile => "blah",
                                 input => \$input2,
                                 output => \$output2

Which on my machine outputs:

$VAR1 = [
             'hello' => 42

Surely this shouldn't happen?
