Since "Net::CIDR::Lite" seems to have it's origins here (can something have multiple origin(s)?), I thought this would be the appropriate place to ask:

Is a Net::CIDR::Lite object safe to use within a threads::shared environment, given appropriate locking to protect object accesses as 'critical code"?

I need to test single IPs against listed CIDRs (a small (<10) set) from within multiple worker-bee threads. The documentation does not address the issue.

I specificly did not use the term "threadsafe", since that implies internal multi-thread protection. I would be using a shared locking variable to insure single thread access.

-----Update------

I went ahead and started coding a small test program. I found that:

my $cidrDB : shared;
my $cidrLock:shared; 

$cidrDB = Net::CIDR::Lite->new;

[download]
threw an error of
"Invalid value for shared scalar at testCIDR.pl line 13."

The 'object' is probably too complex a data type to be shared. So my next approach is that I will create the "our $cidrDB" in the main thread; and use: 

package CIDRDB;
.... #code that runs in worker-bee threads
my $cidrLock:shared; 
sub add_cidr
{
  my $arg=shift;
  {
    lock $cidrLock;
    $main::cidrDB->add_any($arg);
    $main::cidrDB->prep_find();
  }
}

testing continues....
