* however, is that the original error has been buried, and we've received "data" that isn't actually

* TODO: IE9 is rather unfriendly and restrictive with regard to how much data it's willing to
* eval(). In particular, the 10Mb disk image we use for the Windows 1.01 demo config fails in
* IE9 with an "Out of memory" exception. One work-around would be to chop the data into chunks
* (perhaps one track per chunk, using regular expressions) and then manually re-assemble it.
*
* However, it turns out that using JSON.parse(sDiskData) instead of eval("(" + sDiskData + ")")
* is a much easier fix. The only drawback is that we must first quote any unquoted property names
* and remove any comments, because while eval() was cool with them, JSON.parse() is more particular;
* the following RegExp replacements take care of those requirements.
*
* The use of hex values is something else that eval() was OK with, but JSON.parse() is not, and
* while I've stopped using hex values in DumpAPI responses (at least when "format=json" is specified),
* I can't guarantee they won't show up in "legacy" images, and there's no simple RegExp replacement
* for transforming hex values into decimal values, so I cop out and fall back to eval() if I detect
* any hex prefixes ("0x") in the sequence. Ditto for error messages, which appear like so:
*
* ["unrecognized disk path: test.img"]
