 Modified Files:
 	src/tests/lib/libc/gen: t_arc4random.c
 
 Log Message:
 t_arc4random: Verify arc4random works without fds.
 
 It must work in an empty chroot where /dev/urandom doesn't exist, and
 it must work when the file descriptor resource limit is exceeded.
 
 Prompted by discussion around:
 
 PR lib/59117: arc4random has some failure modes it shouldn't
 
 Fortunately these are not failure modes of the current arc4random
 implementation!  But it is important to test them nevertheless, to
 forestall any temptation to invent new failure modes.
