[racket-dev] TR tests sometimes fail with a promise error

Sometimes TR tests fail with the error

force: promise's thread terminated without result or exception

  promise: #<promise:!running!...et/optimizer/run.rkt:47:28>





How can this happen? Is the thread getting killed? Also since this
error doesn't have blame information I don't know if this is an
internal promise error or if TR is misusing the promise library.
