[Mono-list] Mono does not have tail calls?

I had long since held the belief that Mono supports tail calls but when I
recently came to actually test that I discovered that Mono does not, in fact,
have tail calls.
Specifically, I ran the following simple test code:
let even odd n = odd(n+1)
let odd even n =
printf "%d\n" n
let (_: int) =
let rec f n = even g n
and g n = odd f n in
That runs fine in OCaml and F# on .NET but it leaks stack space until it dies
on Mono because the tail calls are not handled properly.
