Do we have a timeline for when this gets removed? If it may be a while, and you
are paranoid others may disregard this warning, you many want to torpedo any
attempts to add this file.

#if !defined(OS_MACOSX)
#error "I sunk your battleship"
#end

Whatever you decide on, do the same in task_manager_browsertest_util.h?
