Comment (by bgamari):

 I have another branch up at https://github.com/bgamari/ghc/compare/bump-
 stack-limit.

 In this branch I,

  * Introduce `getPhysicalMemorySize` to `rts/posix/` and `rts/win32`. Only
 the posix variant has been tested.
  * Fix `RtsUtils.c:stackOverflow` to print the actual stack size instead
 of the stack size limit. This requires a patch in `base`
 https://github.com/bgamari/packages-base/compare/infinite-stack
  * Allow RTS to take `-K 0` to disable the stack size limit. This is a
 hold-over from the last set and should arguably be dropped.
  * Set the default stack size limit to 80% of physical memory
  * Update the user guide appropriately

 Let me know how this looks. It would be great to get this in for 7.8.
