but the intent is still vague for me?

"rtt" is "return from trap".  We were peacefully executing some code -
may be userland, maybe privileged - and took an exception (aka trap)
such as an interrupt, page fault etc.  When the exception has run to
completion we need to resume what we were doing before, and rtt
code is the glue that gets us there.  It also does a bunch of
housekeeping jobs such as checking for signals that need to
be delivered to a process we trapped in, see if time quantum on
cpu has expired, etc.
