Well, that is your shell's issue. 2.01.1(1) works fine on 2.1.107.

RLIMIT_VMEM.

Yes. As I said, it is mmap()ing larger regions. That is not on the heap,
so it isn't counted against RLIMIT_DATA.
RLIMIT_VMEM is for the total mapped address space, including that on
the stack (ie. data segment, ie. set by brk(2)) and that allocated by
mmap(2).
