* Allocate stack space for the given thread ID.
|

*
|

* Each allocation is aligned to 16 bytes.
|
||||
*
|
||||
* Allocations start from the end of onboard memory (0x80400000) and are
|
||||
* allocated right to left.
|
||||
*
|
||||
* The returned address leaves 8 bytes free on the right side of the stack,
|
||||
* presumably for identification purposes. So the actual stack space available
|
||||
* can be 8 bytes above or below what was requested.
|
||||
*
|
||||
* The stack is initialised with the thread's ID. This makes it easier to
|
||||
* identify in memory and detect when a stack overflow has occurred.
