in thread sysread/syswrite wrappers

hat's because readline reads not only from file, but from buffer as well

It's a difference, but it doesn't mean "they don't work". The effect of the pipe buffering -- and file system caching -- means you get the same effects with sysread.

Even sockets have buffers in the tcp stack.
