I added a workaround for that in CVS. Try it out.

I've got 3120 (RH-19) recognized by gnokii as 3100 which is said to be 'breakable'. Without 'allow_breakage = 1' xgnokii enters dead loop straced like this:

futex(0x80e40cc, FUTEX_WAIT, 2, NULL)   = -1 EAGAIN (Resource temporarily unavailable)
futex(0x80e40cc, FUTEX_WAIT, 2, NULL)   = 0
futex(0x80e40cc, FUTEX_WAKE, 1)         = 0
futex(0x80e40f0, 0x4 /* FUTEX_??? */, 1) = 1
futex(0x80e40cc, FUTEX_WAKE, 1)         = 1
futex(0x80e40cc, FUTEX_WAIT, 2, NULL)   = 0
futex(0x80e40cc, FUTEX_WAKE, 1)         = 0
futex(0x80e40cc, FUTEX_WAKE, 1)         = 1

It didn't happen with 0.6.15 - xgnokii just didn't connect.
