fixes #23825; Busy wait on waitid, sleeping at regular intervals (#23826)
Addresses #23825 by using the approaching described in https://github.com/nim-lang/Nim/pull/23743#issuecomment-2199523110. This takes the approach from Python's `subprocess` library which calls `waitid` in loop, while sleeping at regular intervals. CC @alex65536
