It seems to work, but I’m not 100% confident in its lack of bugs. Timing
with 8464.mpd results in about 550ms for loading using fgets and 750ms using
myFgets from above. On the one hand, thats a 50% slowdown based purely on
that one change. On the other hand, 750ms isn’t very long, and while
8464.mpd isn’t exactly a huge file, it’s big enough to prove your point that
the performance is fine.

Just as a proof of the value of disk caching, loading the same model using the
system fgets after a fresh reboot, the same loading portion took 3300ms.
Also, I switched the feof calls out for a check of the value against EOF just to
see if it made a difference, and it didn’t. Within the accuracy of my
measurements, I got the same timing.
