Simulates an error in <init_threadtls> and <free_threadtls>.

helper

sizesignalstack_threadtls

static inline size_t sizesignalstack_threadtls(const size_t pagesize)

Returns the minimum size of the signal stack.  The returned value is a multiple of pagesize.

sizestack_threadtls

static inline size_t sizestack_threadtls(const size_t pagesize)

Returns the default size of the thread stack.  The returned value is a multiple of pagesize.

sizevars_threadtls

static inline size_t sizevars_threadtls(const size_t pagesize)

Returns the size of all local thread variables on the stack.  The returned value is a multiple of pagesize.
