Really? I think the processes would just accumulate and after some time you require a reset. Imho the same way as WSL-1 (unfortunately WSL-2 is still a no go if using citrix hypervisor) works in Windows.
Okay, not really fair. It mostly works but I till get such on reaped, unkillable processed way more often than in a normal linux.
I think they were agreeing with you that it's a problem.
I don't know if it is or not myself, just saying how I read that comment.
