UPDATE: Never mind, I upgraded to the latest XML::Simple-2.14, and it solved the problem. Sorry everyone, that's 2 module updates I screwed up on this week. :-)

Hi, I have a sub that uses XML::Simple to parse an xml file. I tried to put it into a thread, and it would fail with 

thread failed to start: lock can only be used on shared values at /usr
+/lib/perl5/site_perl/5.8.6/XML/Simple.pm line 479.

[download]
So I checked out line 479 and it's just 
 lock($DefaultValues); 
#where $DefaultValues = 1

[download]
So I copied XML/Simple.pm to my local directory and ran it with line 479 commented out, and everything works fine.

So I have a couple of questions:

1. Will I terribly break something without "lock(1)"?

2. Is it possible to make a custom inherited widget of XML/Simple that I can turn locking off, without having to use a customized version?

I'm not really a human, but I play one on earth. flash japh
