Having every backward jump check for thread->aborted
would be a initial "make it work" solution. 

Not to mention that we could have an 
"--expect-no-thread-aborts"  which would
avoid this check ? . for example, when running 
pnetmark ? ;-)

That would be a GCC + (x86/arm/ppc) specific hack ,
which would still not speed it up on all platforms.

But my question is whether , that much work for
just speeding it up in 3 MAJOR platforms is 
worth the effort ;)
