There might be concerns about ensuring data accessibility agains throwing the text file away, but converting to HDF5 would be an elegant for reading in without the memory issues, too (I must confess though, I've regularly read ~ 1GB ASCII files into memory - with decent virtual memory management it did not turn out too bad...)
