longClick() becomes click

[GoogleCodeExporter]

What steps will reproduce the problem?
Did longClick() on a view, and expect the context menu to pop up. However, it 
seems like the longClick() sometimes doesn't click long enough, and it becomes 
a click. When it does this, it fails my test

What is the expected output? What do you see instead?
It should always perform long click

What version of the product are you using? On what operating system?
Espresso 1.1 and Android 4.1.2

Please provide any additional information below.
There's no log indicating that the longClick has become a click
