Opening a Unix mail file folder with fourteen thousand messages takes well over a minute or two on my 2 GHz MacBook. Closing it, after modifying it, takes well over five minutes. IMAIL should be cleverer, either by keeping a cache on disk or by being clever about incremental parsing of the file, and perhaps mmapping it into memory rather than reading it byte-by-byte. When writing, IMAIL should seek to the part of the file that needs rewriting, which requires recording the messages that are dirty.
