Slightly off-topic, but pct (see http://pdos.lcs.mit.edu/cb/pct/)
provides the functionality of Plan 9's tprof and, like tprof, doesn't
require recompiling. It probably wouldn't have found your problem
(ls wasn't the one chewing cycles), but I've found it much more
useful than gprof. The invocation is a little odd. It really needs a
better wrapper.
