FS I/O is a blocking operation (even writes can be blocking, but
more normally only reads out of cache are blocking) so reading the files
would stall the whole server while you wait for I/O to complete. So it's
ok for small projects where performance isn't a big issue, but it should
be generally discouraged since it breaks the async model of twisted. If
you really want files, you should consider doing all blocking I/O in a
separate thread.
