Does garbage collector properly dipose of os/spawned processes?

Does it if I don't close it?

A spawned process can have streams attached to it.

Apparently, if I don't manually close spawned processes, CPU consumption skyrockets, and orphaned spanwed processes with attached streams aren't closed by garbage collector.

Am I correct?

This is turned into an issue.
