Uhm, what is the purpose of #sysread.
In other words, when would I use it instead of just #read.
I've done some searching, but have found nothing concrete.

When you know neither a length nor a terminator of data available.
For example, telnet.rb uses IO#sysread. It reads from network until a
shell's prompt. But the length until the prompt is not known in
general. Also the prompt varies. If IO#read is used and longer
length is specified, it blocks forever.
