Typing keys quickly may not open the popup correctly.

Warning: I will close the issue without the minimal init.vim and the reproduction instructions.

Problems summary

Typing keys quickly may not open the ddc completion window correctly. It seems to be reproduced when there are many candidates. I'm using skkeleton here for reproduction, but I think it's a problem that can occur with other sources. Thanks.

Expected

Even if you type the key quickly, popups open correctly.

[Shougo]

The cancel is reproduced. But it is ddc problem? Really? I will check it later.

[Shougo]

Oh, it is ddc's lock/skip feature. But it is required to completion lockup.

[Shougo]

I have removed the feature.
