CGI::Fast and ithreads.

Hi, everybody!

I'm writing a CGI application and am going to use ithreads in order to 
reduce execution time. Is it possible with CGI::Fast? I get segmentation 
fault every time I'm using threads with CGI::Fast.

Simple demonstration:

[kosov@yoyo ~]$ cat test.pl
#!/usr/bin/perl -w

require threads;
require CGI::Fast;

my $thr = threads->new( sub {print "I'm a thread.\n"} );
$thr->join();

[kosov@yoyo ~]$ perl test.pl
I'm a thread.
Segmentation fault

What's wrong? Did I forget something to do?


Also sometimes I get error messages like:
Attempt to free non-existent shared string 'NLS_LANG', Perl interpreter: 
0x8a962f0 during global destruction.
Attempt to free non-existent shared string 'HOME', Perl interpreter: 
0x8a962f0 during global destruction.
...


Thanks in advance.
Any help, link, etc. will be greatly appreciated.
