Bugs:
o If you forget to call Open(), it segfaults
o No data writeout until compact?
o Inserting 100,000 blocks is horribly slow (I know, you're
fixing it) -- it's still running, now at 17 minutes, and
only 52,000 blocks...39:00 - 79,000 blocks...
44:00 - 84,000... all in all, it took 1:19:20 (yes, over
an hour!) and ate over 5 megs of RAM. And it created a blank,
46-byte file! Who ate my data?!
o To long string at prompt = segfault (buffer overflow!)
o Adding blocks is in quadratic [ O(n^2) ] time! This is a crime
against humanity! (tester to prove this attached)
o Destructor did not write data to file -- was it supposed to?
Or must I call close()?
o Constructor did not open file -- it should, to be simular to
an fstream.
o No man file
o No configure file to set up XEndianFile
