`run` command spawns a new process and never kills it

[winderica]

Every time run/-c command is executed, it spawns wslhost.exe, which will never be killed:

• Before executing Arch.exe run "echo 'test'"
• After executing Arch.exe run "echo 'test'"

While other distros (not using wsldl) don't have this problem:

• Before executing ubuntu2004.exe run "echo 'test'"
• After executing ubuntu2004.exe run "echo 'test'"

It's quite annoying because when there are a lot of wslhost.exes, launching a new terminal of wsl will fail and complain The Windows Subsystem for Linux instance has terminated.

It seems that this is not a bug of wsldl. (Although I could not figure out what goes wrong exactly)
