This seems a perfectly reasonable space/time tradeoff (obviously the
above approach can end up using more space, but can save considerable
time). Possibly a good alternative is to provide user control over
this tradeoff.
Another good idea for unbounded strings is to implement automatic
garbage collection for just this type. That's also somehting we have
looked at in some detail.
