config PTHREAD_RECYCLER_DELAY_MS
	int "Delay for reclaiming dynamic pthread stacks (ms)"
	default 100
	help
	  Prior to a POSIX thread terminating via k_thread_abort(), scheduled
	  work is added to the system workqueue (SWQ) so that any resources
	  allocated by the thread (e.g. thread stack from a pool or the heap)
	  can be released back to the system. Because resources are also freed
	  on calls to pthread_create() there is no need to worry about resource
	  starvation.

	  This option sets the number of milliseconds by which to defer
	  scheduled work.

	  Note: this option should be considered temporary and will likely be
	  removed once a more synchronous solution is available.

config POSIX_PTHREAD_ATTR_GUARDSIZE_DEFAULT
	int "Default size of stack guard area"
	range 0 65536
	default 0
	help
	  This is the default amount of space to reserve at the overflow end of a
	  pthread stack. Since Zephyr already supports both software-based stack
	  protection (canaries) and hardware-based stack protection (MMU or MPU),
	  this is set to 0 by default. However, a conforming application would be
	  required to set this to PAGESIZE. Eventually, this option might
	  facilitate a more dynamic approach to guard areas (via software or
	  hardware) but for now it simply increases the size of thread stacks.
