Gawk will keep on reading:

$ seq 3 | gawk '{ print "<" $0 ">"; system("sleep 1") }'
<1>
^C<2>
<3>

Same for nawk, mawk quits.

$ seq 3 | mawk '{ print "<" $0 ">"; system("sleep 2") }'
<1>
^C


Also worth noting, gawk exits with 0 in this case:
$ seq 3 | awk '{ print "<" $0 ">"; system("sleep 2") }'
<1>
^C<2>
^C<3>
^C

This doesn't look correct...
