This was fixed in 2.054. There were several cases where reading or writing a
single array element could cause the entire array to be copied! These cases
have now been fixed, giving an order of magnitude improvement in memory use and
compilation time. (The original test case (concatenation) hasn't changed; it's
simply caused by absence of a compile-time gc).
This bug is now a far less serious problem than bug 6498.
