On macOS, pthread_attr_setstacksize requires the stack size to be a multiple of the system page size. The previous changes here assumed the use of pthread_attr_setstack, however the transition to pthread_attr_setstacksize means we can avoid rounding the pxEndOfStack pointer. This is additionally positive because pxEndOfStack was actually being rounded in the wrong direction -- it ought to have been rounded down (_trunc) instead of up due to the stack growth direction. In my case this actually caused pxEndOfStack to end up after pxTopOfStack, which underflowed and created a huge stack size request + EXC_BAD_ACCESS in pthread_create.

Each real time kernel port consists of three files that contain the core kernel components and are common to every port, and one or more files that are specific to a particular microcontroller and/or compiler. + The FreeRTOS/Source/Portable/MemMang directory contains the five sample memory allocators as described on the https://www.FreeRTOS.org WEB site. + The other directories each contain files specific to a particular microcontroller or compiler, where the directory name denotes the compiler specific files the directory contains. For example, if you are interested in the [compiler] port for the [architecture] microcontroller, then the port specific files are contained in FreeRTOS/Source/Portable/[compiler]/[architecture] directory. If this is the only port you are interested in then all the other directories can be ignored.
