    runtime/pprof: make TestBlockProfile less timing dependent · 121c434f
    Richard Miller authored
    The test for profiling of channel blocking is timing dependent,
    and in particular the blockSelectRecvAsync case can fail on a
    slow builder (plan9_arm) when many tests are run in parallel.
    The child goroutine sleeps for a fixed period so the parent
    can be observed to block in a select call reading from the
    child; but if the OS process running the parent goroutine is
    delayed long enough, the child may wake again before the
    parent has reached the blocking point.  By repeating the test
    three times, the likelihood of a blocking event is increased.
    
    Fixes #15096
