Tomo-san,

AFAICS signalfd has not been backported to Red Hat's RHEL 5 kernels. So
if I understand correctly, this patch would break building tgt on that
platform (and presumably others, like Debian etch and SLES 10). Would
you mind employing ifdefs so that when signalfd is not available on the
platform tgt is being built on, it reverts to the old behavior?

Just my $.02.

Cheers,
Florian
