* helm.el (helm-compute-matches-internal): Issue #160 Use while-no-in…
Here a first shot, give it a try with e.g helm multi occur with many buffers and add remove characters in pattern continuously and fast.(and compare with previous version)
I have changed the place of while-no-input because it should not be used in async sources, have a try.
Ok so now we use while-no-input in helm, thanks for the tip, closing bug, feel free to reopen.
