### Steps to reproduce

The problem seems to occur when I activate a tab for any source file in a particular project, or a tab for a higher level project that depends on that project. The CPU goes high and stays high.

The project is called `Client`, so you can find it in the provided trace logs.

Unfortunately, it is not open source, and it may become commercially valuable at some point, so I'm not happy to provide the source itself, but I can try experiments to track down the problem.

### Details

I expect the CPU to go up for a second or two while `FsAutoComplete` does it's parsing, but it stays high indefinitely. VSCode is still usable but my fan is blowing. If I close the source file tab and restart VSCode, the CPU is back to normal, but then when I open the file again, the CPU goes high and stays high. It is typically over 20%, but sometimes only around 10%.

The memory is also high, around 1.2GB while I was watching it in the System Monitor.
