Helm is starting updating (create the first process) after the
`requires-pattern' value of source, for locate it is 3, so when entering
the third char in pattern the process start, return the data through a
process-filter, then stop the process-filter (setq *filter t) and kill
the process. When you enter the 4th char, a new process is created,
killed and so on.
You can avoid this by hitting `C-!' when starting helm session, then you
can type the whole pattern quietly and hit `C-!' again when done to
launch process, in this case only one process will be started.
(You can also type `C-!' at anytime to interrupt process too long to
finish, type more input and restart process again with `C-!')

This was just for info in case that help for debugging.
