It looks like necessary fault doesn't occur timely.

The above two commands involve following operations and two faults:
        ubc_uiomove for write
        uao_put(PGO_FREE)
        ubc_uiomove for write
        ubc_uiomove for read

When the 2nd faults occurs during 2nd ubc_uiomove for write, resulting
file contains correct text.  On failure case, the 2nd fault occurs
during ubc_uiomove for read.
