threads with PerlQt

I've been trying to get a multithreaded app working with PerlQt to no 
success whatsoever and was hoping someone could help me out.  It seems 
there's no perl implementation of QThread, and interpreter threads cause 
redundant garbage collection or some such ("attempt to free non-existant 
shared string...").

Through much internet searching, I found something saying a possible 
solution is to spawn a thread off the main thread for the GUI and spawn 
no threads from that one, spawning all other threads off the main 
thread.  I tried this to no success.

If anyone has any pointers for multithreaded perlqt apps, I'd appreciate 
it greatly.  Even a hint toward some overlooked documentation would be 
useful.

Thanks,
