One such case is Cygwin --- I'm not sure how "contrived" it is. Cygwin
has an old-fashioned non-COW fork, and to add insult to injury,
process creation generally is very slow (~100ms). It pays to eliminate
subshells in that environment.
Given what Cygwin has to work around in Windows -- it is very contrived.
MS has copy-on-write available to MS processes, that it's not usable in
Cygwin isn't surprising given that most of Windows is closed-source.
But if you really want bash on your windows, use a native copy. It's
not as likely to have the same problems

Apparently there is a Windows Subsystem for Linux that is currently in Beta
for Win10:
