WSL 2 consumes massive amounts of RAM and doesn't return it

* Your Windows build number: 18917 * What's wrong / what should be happening instead: WSL 2 starts using huge amounts of RAM after a while, just using it like normal. At the moment I'm using phpstorm, and did a dump/load of a database. `Vmmem` is using 7 GB of my 16 GB of RAM and not returning any, even though Ubuntu is actually using much less. I have seen it grow until nearly 100% of my system memory is in use, and it will not release it until I shut down the WSL 2 VM. This may or may not be related to #4159 ``` corey@Corey-Laptop:/mnt/c/WINDOWS/system32$ vmstat -s 15235516 K total memory 920348 K used memory 1886048 K active memory 6434312 K inactive memory 6606548 K free memory 76280 K buffer memory 7632340 K swap cache 0 K total swap 0 K used swap 0 K free swap 163729 non-nice user cpu ticks 298 nice user cpu ticks 13177 system cpu ticks 68988300 idle cpu ticks 8962 IO-wait cpu ticks 0 IRQ cpu ticks 10022 softirq cpu ticks 0 stolen cpu ticks 1481417 pages paged in 6792976 pages paged out 0 pages swapped in 0 pages swapped out 1079177 interrupts 5131981 CPU context switches 1560599814 boot time 8772 forks ```
