Okay the I think the trouble is in `comp-delete-or-replace-file' when
gets called from `comp--compile-ctxt-to-file' (probably through
`comp-clean-up-stale-eln').

There's some specific Windows handling for shared that can't be removed
because still loaded.

PS can't you kill the sub processes?  Or the main Emacs is hanging?
