Well, it doesn't on my system:

/home/wolff> dd if=/dev/zero of=/dev/null bs=1k &
[1] 14276
/home/wolff> kill -URG %1
/home/wolff> kill -URG %1
/home/wolff> kill -URG %1
/home/wolff> kill -URG %1
/home/wolff> kill -URG %1
/home/wolff> kill -INT %1
/home/wolff> 3960638+0 records in
3960637+0 records out

[1] Interrupt dd if=/dev/zero of=/dev/null bs=1k
/home/wolff> cat /proc/version
Linux version 2.2.14pre1 (wolff@cave) (gcc version egcs-2.91.66 19990314/Linux (egcs-1.1.2 release)) #1 SMP Sat Oct 30 11:59:50 MEST 1999
