      Solaris only bug.

      Running the jck swing interactive tests under javatest in singleJVM master/agent mode will result in test failures due to OutOfMemoryErrors because repeated
      calls to jFFBMmapDevice exhaust the available address space.

      See bug 4295723 for the intial report of this problem and some information
      on reproducing the failure with javatest. That bug reported a hotspot vm
      crash due to the address space exhaustion. The vm crash has been fixed,
      but tests still fail with OutOfMemoryErrors because of the address space
      exhaustion.

      ============================================================================

      Upon fixing the bug #4295723, John Coomes made a fix to the vm. Please see
      the attachment for his version of the vm as of 1/4/2000.
