I added this to the top of one of my OpenGL apps: 

#! perl -slw
use strict;
use threads;
use OpenGL qw[ :all ];

async{ print 'from thread' }->detach;
...

[download]

And I get: 

c:\test>GLex7.2.pl
Can't locate package GLUquadricObjPtr for @OpenGL::Quad::ISA at c:/Per
+l/lib/threads.pm line 117.
from thread
display
display
...

[download]

The app runs without problems (other than the error message), but it probably indicates that OpenGL isn't thread-safe.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
"Too many [] have been sedated by an oppressive environment of political correctness and risk aversion."
