      runtime: make TestStackGrowth a serial test · 286599f2
      Austin Clements authored
      TestStackGrowth is currently a parallel test. However, it depends on a
      20 second timeout, which is already dubious in a parallel test, and
      became really problematic on slow builders when runtime.GC switched to
      triggering concurrent GC instead of STW GC. Before that change, the
      test spent much of its time in STW GC, so it wasn't *really* parallel.
      After that change, it was competing with all of the other parallel
      tests and GC likely started taking ~4 times longer. On most builders
      the whole test runs in well under a second, but on the slow builders
      that was enough to push it over the 20 second timeout.
      
      Fix this by making the test serial.
      
      Updates #19381 (probably fixes it, but we'll have to wait and see).
