There was a problem hiding this comment.
Looks reasonable.
The CacheHostTableConfig is allocated on scheduling the event and nobody owns the pointer.

Fixes a memory leak when reloading hosting.config.
I manually tested and ran, modified hosting.config and reloaded. Appears to work, requests and things continue to work, debug prints in the constructor and destructor show a new
CacheHostTableConfigbeing allocated on reload, and the old one being deleted once and only once.Recommend backporting to All The Things. Appears to have been a bug forever.
