Comment (by olli):

 Replying to [comment:6 Christian Maaser]:
 > Actually, due to the assumptions of _chkstk/Windows use of
 fixedsize_stack should be discouraged and shouldn't be default on Windows,
 but that is a different issue.


 A solution for fixedsize_stack could be to use
 {{{
 VirtualAlloc()
 }}}
 as in protected_fixedsize_stack but without adding a guard page at the
 end. On Windows the minimal stack size must be of page size.
 So fixedsize_stack would allocate a stack of mulitple pages size.
