* Implementation of functions defined in portable.h for the Posix port.
*
* Each task has a pthread which eases use of standard debuggers
* (allowing backtraces of tasks etc). Threads for tasks that are not
* running are blocked in sigwait().
*
* Task switch is done by resuming the thread for the next task by
* sending it the resume signal (SIGUSR1) and then suspending the
* current thread.
*
* The timer interrupt uses SIGALRM and care is taken to ensure that
* the signal handler runs only on the thread for the current task.
*
* Use of part of the standard C library requires care as some
* functions can take pthread mutexes internally which can result in
* deadlocks as the FreeRTOS kernel can switch tasks while they're
* holding a pthread mutex.
*
* Replacement malloc(), free(), calloc(), and realloc() are provided
* for glibc (see below for more information).
