    A specialized abstract test case class for writing

    VM crash tests. The test is run in separate process

    if it eventually crashes the VM, it won't take whole test

    suite with it.

    Each test case *must* be annotated by one <spawn:> annotation,

    argument must be either `true` of `false`. If `true` then the

    test is run in a freshly started VM. If `false`, test is run

    in the same VM.

    As this is meant as a base class for regression tests that used to

    kill the VM, normally you should annotate tests with <spawn: true>
