what's the best way to find the set bits in the output from select? I really didn't want to do a brute force loop over every bit in the vec. Would something like this be faster?
perl -le '$vec = pack "N", 0xF00F0001; $a = unpack ("b*", $vec); print $a; while ($a
=~ /1/g) {print pos ($a)-1}'
00001111111100000000000010000000

is there an "official" cunning recipe for this?
