Asynchronous spell checking is disabled by default (bug 81042). It means all requests of checking the string are sent synchronously.
WebKit-EFL implements requestCheckingOfString method (bug 108172) which allows to call spelling checking asynchronously.
We should enable it be default for EFL to use non blocking API.
