Bugzilla #40387:

Dealing with IOExceptions for certain large PFM files in a more radical way: load everything into memory, since we basically need random access here. The biggest PFMs I've seen so far are around 20KB so this shouldn't be a big problem, especially as the memory is freed pretty quickly.
