Various string crashes

[pcmacdon]

It looks like jsish is failing to check/enforce some of the basic string limits, and crashes instead of erroring out.

var s = 'abcdefghijklmnopqrstuvwxyz';
try { s.repeat(9999999);
} catch(e) { puts('repeat fail', e); }
while (true)
   s += s;

Should be fixed no.

DString does not error out when limits are exceeded, by design. It truncates to the max and prints an error. This should mean incorrect results at the boundary, but not crashes.

There could be more, so am leaving this open for a while.
