The frysk.sys.StressMapRead.testMapRead test gets run by make check but takes
over half on our on a 32bit machine and even longer on a 64bit machine. This
makes this test completely impractical to keep enabled if we want people to
actually make sure make check results are always clean.
For now this test is disabled till either the test is rewritten to only test the
functionality that might be broken (start and end of a Map can be read
correctly) or there is a new make target for just the stress tests that can be
run independently from the make check unit tests.
Test deleted; instead covered by ptrace peek/poke tests that check for
misaligned and various sized transfers.
