# Verify that we remove inserted breakpoints before detaching.  The basic steps
# are:
#
#  - Use "set breakpoint always-inserted on", to keep breakpoints inserted when
#    stopped.
#  - Set a breakpoint in the GPU code and run to it.
#  - Detach
#  - Watch for existence of a file the detached process writes if the GPU code
#    ran to completion and gave the correct result.
