This is not practical if the generated stream is very large. For
example, when I do this kind of testing on a memory allocator, the
number of requests might well be in the millions or billions.

Even if the disk space existed to store such, the time needed to read
it in would dwarf the time needed to regenerate the stream with the
random number generator.
