[IronPython] Default recursion limit

Hello all,
For IronPython the default recursion limit is maxint: 2147483647
This is too deep for .NET - and infinite recursion causes the process to
be terminated with a stack overflow exception.
You can fix this by calling "sys.setrecursionlimit(something)" with
something sensible - but an unfeasibly large value as the default seems
incorrect (?).
There is a further performance related issue. Generally IronPython is
much faster for recursion due to lower overhead in function calls. For
recursion depths of about 5000 though, IronPython takes *much* longer to
raise an error than CPython (about 10 seconds as opposed to half a
second or less).
