...oh, but that issue in particular was more straightforward, and should now be fixed.

so it is!!!!! i'll have to make another change to use that in test_isolated_process.py

...i think i already did, heh.

well i merged master recently and there's e.g.

javac_version_proc_req = yield Get(
    ExecuteProcessRequest, JavacVersionExecutionRequest, javac_version_command)
  javac_version_proc_result = yield Get(
    ExecuteProcessResult, ExecuteProcessRequest, javac_version_proc_req)

instead of

javac_version_proc_result = yield Get(
    ExecuteProcessResult, JavacVersionExecutionRequest, javac_version_command)

i deleted the other rule
