clicked at least once. Fixed by calling setFocibleInTouchMode.
Fix bug where control keys didn't work with the soft keyboard.
Fix some warnings reported by Eclipse IDE. (Missing @Overrides, needless
imports, unused variables.)
Explain how it's different than ProcessBuilder

descriptor.
Note in the doc comment that the implementation relies on a private
FileDescriptor API.
Also remove an unused method.
