Opening ndtiff dataset in two different processes

[ieivanov]

Hey @henrypinkard I would like to open a ndtiff Dataset that is currently being acquired in a separate process for viewing with napari. I need to do that because I am running two Acquisitions in parallel and would like to view the data from both. Do you see a problem with opening a current dataset in a different process? Would the builtin thread lock protect from read/write conflicts?

If you open it by just passing the path to it (i.e. not using image saved callbacks), then there should be no problem because it is read only. However, you will keep having to reopen it, because the index will be read once opening and then not updated unless you repoen

Great, thanks! I also saw that I have to keep reopening the dataset, as you described, which is not really a problem. And I get a warning that the dataset is not complete, which is also expected. I'm stress testing it now to make sure nothing really breaks
