I'm reluctant to make the test suite more sensitive to the environment
it's running it.  Is the reason to do this that the test can time out
normally, and so we'd like to avoid lengthy timeouts?  If that's the
case, can the test be fixed somehow instead?

I guess my mental model here is that a timeout should not matter unless
a test is flaky.  But maybe that's naive?  I don't know :-)

Tom> +proc with_timeout_factor { factor body {body_uplevel 1}} {

I think body_uplevel shouldn't be needed.

Tom> +    return [with_timeout_factor $factor $body 2]

... since this can just do

    return [uplevel [list with_timeout_factor $factor $body]]

thanks,
Tom
