Repro Steps

Run WSL for a number of days without restarting, it gets slower and slower.

Today I was really noticing it so ran a test, a refactor I'd been developing which is some shell, perl and golang reported by time:

real 6m51.373s
user 0m21.999s
sys 0m3.586s
After closing wsl and restarting with wsl --shutdown the same thing took:

real 0m42.377s
user 0m34.388s
sys 0m14.403s
Before the restart vmmem was using 22GB of RAM, afterwards 2.3GB

Expected Behavior

WSL should not slow down after time

Actual Behavior

Significant slowdown and significant memory usage just be using it for a few days.

This is just a re-post of #9137 which was closed by the bot without resolution, really should ditch that as its just causing repetition of details, forcing users to recreate bugs losing the original context.
