31980d4fb9 Don't bother clearing the Magic string when the magic number 
can't be read, since it isn't cleared on other error paths.

91a7dd7cb6 Don't bother checking canRead() before calling getMagicNumber(); 
getMagicNumber() does its own error checking.

616845c384 Eliminate the use of PriorityQueue and just use a std::vector, 
implementing pop with a linear search for a "best" element. The priority
queue was a neat idea, but in practice the comparison functions depend
