Description
This is after the other performance fixes in 1.19.3. I've seen up to 5 seconds extra on Windows with a large workspace. Longer delays might be possible Linux and Mac or slower machines (not sure yet).
This might be fixable via preventing other threads from updating the database if a document or workspace symbol search is in progress.

Research direction
Start by reproducing the delay on Windows with a large workspace while files are being tag parsed, comparing workspace symbol searches with and without concurrent parsing. Investigate how symbol search and tag-parser database updates interact; done means the extra multi-second delay is no longer observed.
