The length of time it took for the microkernel's test_fp_sharing test to run
was occasionally causing issues with sanity_chk. The test would take close
to five minutes to finish and sanity_chk has a five minute timeout for the
tests. To resolve this, the number of iterations for which the test executes
has been cut in half (from 1000 to 500).
