Note that poisoning qsort outlaws vec::qsort too; it would need to be mass-
renamed as well (to vec::sort, presumably).  It seems there are 83 or more
calls to vec::qsort.

I believe qsort_chk isn't appropriate, checking is not explicitly a part
of interface, and we never use _chk in potentially-checking tree and RTL
accessors either.

Thanks.
