Error "414 Request-URI Too Large" when deleting users in bulk

[sirzooro]

Steps to reproduce:

• add many users (I added 600);
• go to user list, change screen options to display all of them;
• select all of them and execute bulk delete

Looks that user list is send using GET instead of POST, hence this error. I did not check if other lists have the same problem when bulk action is executed on many items.

WP 4.0-beta2-20140728 is also affected.

Did you take a screenshot of the error as well?

This was standard Apache error page, so I did not take any screenshots.
