just a quick comment: there may be a problem with Tie::File if the file is somewhere far far away.. for all that we know, E: might be a mapped network drive that takes several seconds to respond..

while we can solve half the problem by deferring the writing of the tied file, we can't do much about the reading - and we certainly don't want to rely on having disk space nearby. In this case loading the entire file to memory might be the only reasonable solution...
