In core.thread I don't see a portable way to pin a thread to a 
specific core, or at least pin the thread to whatever core it is 
currently running in.

I found this solution, but it's for Windows only.

http://www.gamedev.net/blog/1140/entry-2254424-setting-thread-affinity-on-windows-in-d/

I can find solutions for pthread coded in C/C++, but I'm not sure 
how to apply these solutions when using the D Thread class. I may 
be able hack something out, but I need to be sure it's safe and 
correct.

Any help is appreciated.

You should file an issue [0] as this should actually be in 
core.thread.

I filed an enhancement request for the thread module.

Digging deeper, I notice that module core.sys.posix.pthread is 
missing the affinity related functions, so I'll file that as a 
bug.
