On FreeBSD 5:

  49165
  -e:1:in `inspect': stack level too deep (SystemStackError)

I think I can live with that.  Solaris 9 fares somewhat worse:

  3921
  -e:1:in `t': stack level too deep (SystemStackError)

But not as badly as Linux 2.6.8.1:

  2091
  -e:1:in `p': stack level too deep (SystemStackError)

Or WinXP:

  1330
  -e:1:in `p': stack level too deep (SystemStackError)

I wonder, is it safe to rescue SystemStackError?  It seems to work, but
can the interpreter be trusted after this?
