"Checkpointing long" on exit

Why is this happening?

Xubuntu 20.04
Audacity 3.0.0 2c47dc5
<https://github.com/audacity/audacity/commit/2c47dc5ba1a91c87a457ffba6caf8b1baf706279>
PC laptop has system installed on SSD
Additional data storage on internal hdd.
Audacity temp folder is on SSD.

Importing large WAV from hdd:
1. Launch Audacity
2. Drag and drop large WAV file (2.4 GB) from hdd into Audacity.
Import takes about 45 seconds.
3. Exit Audacity
3.1. "Save project before closing?" -> No
3.2 "Checkpointing long" dialog opens and may take 30 seconds before
Audacity closes.

Why is Audacity doing "checkpointing"?  What is it actually doing?

If I wait a couple of minutes after the file has fully imported before
exit, Audacity closes immediately. Does this mean that Audacity is actually
doing part of the import process in the background after the waveform has
appeared?

Importing from SSD:
1. Launch Audacity
2. Drag and drop large WAV file (2.4 GB) from SSD into Audacity.
Import is MUCH slower (around 1 minute 30) ???
3. Exit Audacity
3.1. "Save project before closing?" -> No
3.2 Audacity closes immediately.

Why does import from SSD take twice as long as from a much slower hdd?

Peter has also reported slower import from his SSD on Windows, though I
don't know the exact details.
