[erlang-questions] Tool for performace evaluation

[Ahmed Omar]

.does your sorter:go involves creating a link? (using start_link,
spawn_link, ... etc)
if yes, I believe this might be a bug in percept, as it doesn't tag the
result messages and doesn't use a selective receive
as a workaround, try
spawn(percept, analyze, ["test.dat"]).
