You wouldn't miss a slowdown. Your tests still run at the same timeout.
o Single test architecture slowdowns are handled with:
sysdeps/<arch>/Makefile => xxxxx-ENV = TIMEOUT=YYYY
o Scaling the *entire* testsuite timeout defaults are done with
a global environment variable. Such is suitable if you decide
to run on a box that is 2x faster, or 4x slower, and you want
to scale the timeouts accordingly.

For future reference and timing considerations, it's an rp2430.
Linux's idea of user<->page mappings doesn't match the architectures
hardware implementation, thus munmap is slow because we need to flush
all the aliased address mappings.
