Deadlocks when saving and instantly closing a file

[kno10]

Bug report

I still get deadlocks that make using Texlipse really annoying.

I have found a reproducible way to trigger them (on my machine):

I open a (long enough, real) document, insert a \label{} at the top and immediately press Ctrl+S Ctrl+W to save and close the file.
This causes Eclipse to completely lock up, I have to kill the process.

If I wait a second before closing the window (there is probably the parser triggered to update the outline, etc.) then it is fine.
But often I have one very simple change to make in several file (e.g., adding a \label{} to each section), I have the "habit" of saving-and-closing them with shortcuts. I lock up Eclipse all the time, and I have been now using vim to edit the files instead.

Please describe your environment:

I just updated Eclipse, it still occurs.

• TeXlipse version: 1.5.0
• Eclipse version: 2023-03 (4.27.0)
• Linux GTK
