No there are no plans. I understand that could be useful for POSIX 
platforms, but you should have a portable solution for other platforms.

Good initiative. I believe that we could start by an implementation for 
POSIX. We will need the code, tests and updated documentation. It will 
be even best if you fork the github repository and propose a PR.
