[dsdp-tm-dev] Committers please vote: API changes on RSE?

Dear committers,

Dave McKnight has proposed an API change to the IRemoteFileSubSystem and IRemoteProcessSubSystem in order to add progress monitors to some method calls, such that there is a chance to cancel long running operations.

My personal take is, that although its already very late in the game I'd like to accept such API changes because it appears that
1. We dont have many clients on openRSE yet. At least none that I'd know of.
2. Those API changes appear simple and straightforward.
3. API changes will become much more difficult than now as soon as we have 1.0 released, so better do it now than in the future. 4. The API changes will enable our users to write interruptable services, i.e. allow something not possible today. So even if our own services are not all interruptable yet, it's important to open up the API for allowing interruptable services in the future.

Considering all this, I'm voting +1.
Committers please cast your votes.

1) I did consider putting this to a vote but then thought it was too trivial a change for that. It was really something that should have been done from the start but it was an oversight. At this point I haven't committed anything since I wanted to see the reaction to my email and I guess that was a good thing.

2) I was wondering about the order of arguments too - I suppose the last argument is consistent with RSE, although, I'm not sure how consistent it is with other things. I guess the natural thing would be to place it at the end. I would like to make the corresponding changes to the list*() APIs for IRemoteProcessSubSystem as well. I'm still not sure whether we should have monitors for all the methods right now without taking a closer look at their usages. I'm wondering if maybe we ought to phase this in two parts: first to deal with queries (the most obvious case) and second phase to deal with the other subsystem calls. Any thoughts on that? Before getting into the details, I suppose we may as well have a vote on whether or not we should make any API changes at this point.
