 A note about not making recursive calls: I made a mistake in my
 report; the tail instruction is for non-recursive tail calls.  It's
 standard practice to compile tail recursive calls into unconditional
 branches to the top instead.

+It is probably a bit hard to detect if the tail call can actually be
+done in mcs.
+There is already a jit optimization, -O=tailc, which you can enable
+(though this isn't supported, and may not catch all cases).
+About xplatform, what I am saying is that if you rely on -O=tailc,
+your program won't work on the msft jit unless they do something similar.
+In general, c# compilers don't make optimizations for recursive styles
+of programming as most people just don't do that in c#.
