It would appear we'll run into similar problems with mmap() if

 - a device (ipod, external harddrive, usb stick) is removed/unplugged
   while still in use

 - an mmap()'ed file is truncated


There don't seem to be many possibilities of handling these things gracefully.
Installing a global signal handler isn't really an acceptable thing to do for a
library (but even then it would be fairly complicated to deal with it).


Maybe we should just default to normal read() again? The performance win of
mmap() is probably negligible compared to the cpu time used for audio/video
decoding/encoding. Shame about the additional memory usage though...
