The delay parameter has 'int' type while explicit int32_t is used in sigtimedwait() (sig_timedwait.c) This can lead to wrong argument for systems that have default int size different than int32 (namely AVR).

Logic for delayed memory garbage collection for the case of user space memory will not work as implemented for the case of the kernel build. That is because the correct context is in place in order to free the user memory when sched_kufree is called, but will not be in place later when the memory garbage collection runs. If this feature is really needed, then some more substantial redesign is required
