+ * 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).
+ *
+ * stdio (printf() and friends) should be called from a single task
+ * only or serialized with a FreeRTOS primitive such as a binary
+ * semaphore or mutex.
