Actually, the size of the stub is the effective minimum - even if you 
stubedit 512 bytes you will end up with something like 2100 bytes (but it's
a very odd size, NOT a factor of 512).  So you can be guaranteed the
transfer buffer will be at least 2048 bytes.  I/O performance may be very poor
if you pick a value less than 4096, however.
