Long delay when processing delete requests of recently uploaded items. about amsmb2

[Kaito0597]

Update: I think I might have found the cause, and it's a weird one. In the course of testing my app, I will usually have MacOS's Finder window open to the root directory of my Samba share where I am testing the various file operations of my app such as uploading, renaming, deleting, and so on, just so I get instant feedback and make sure that they went well. As it turns out, for some reason, having the MacOS Finder window open, and looking at a share, delays at least the deleting operation from occurring. And only on newly added files. A very specific edge case I know. I have tested this a few times with the Finder window open and closed in combination with a SSH terminal and the good ol' fashion ls command to verify that the file was deleted, and each time the window was open, there would be a large delay, and each time it was closed, there wouldn't. I don't know if this is an issue with the framework or MacOS's implementation of the SMB protocol, but I am leaning towards the latter given how strange it is. I am going to leave this open just for the time being and continue working on my app since there will most certainly be many more deletions, and set up something that will notify me if the file sticks around any longer than it should, and if it does, I'll know that this is all just a strange coincidence. If in about a week, it hasn't occurred, I'll close this issue.
