- * The standard glibc malloc(), free() etc. take an internal lock so
- * it is not safe to switch tasks while calling them.
- *
- * Requiring the application use the safe xPortMalloc() and
- * vPortFree() is not sufficient as malloc() is used internally by
- * glibc (e.g., by strdup() and the pthread library.)
- *
- * To further complicate things malloc() and free() may be called
- * outside of task context during pthread destruction so using
- * vTaskSuspend() and xTaskResumeAll() cannot be used.
- * vPortEnterCritical() and vPortExitCritical() cannot be used either
- * as they use global state for the critical section nesting (this
- * cannot be fixed by using TLS as pthread destruction needs to free
- * the TLS).
- *
- * Explicitly save/disable and restore the signal mask to block the
- * timer (SIGALRM) and other signals.
