Taken the vast amount of threads you'll need, there will be a big
overhead.

I urge you to actually try it and see for yourself. From my experience,
it sucks... even when only doing 1 port it takes hours regarless of what
the man page implies.
I'll figure it out, thanks, Tubby.

One last things... here's a *very* small sample netstat output from a
threaded py script:
tcp0 1 192.168.1.100:41066 192.168.17.132:www SYN_SENT
tcp0 1 192.168.1.100:46412 192.168.5.132:www SYN_SENT
tcp0
