introduced a timing bug in YahooClient. The bug will
trigger as follows:

1) YahooReadThread calls RawPacketInputStream.readPacket()
2) Some data comes in, but not the whole packet
3) YahooClient.SO_TIMEOUT elapses
4) YahooReadThread continues, and starts readPacket() again
in the middle of the previously pending packet.

and thus loses synchronization with the stream.

I'm not sure what behavior will ensue, but the fix is
something like follows:

1) Create wtanaka.net.SocketInputStream, referred to as
"wnS" for short below
2) add method wnS.read() which will poll
Thread.interrupted() using SO_TIMEOUT and throw a
InterruptedIOException if interrupted() ever becomes
true.
3) back out change made to Socket, YahooClient and
YahooReadThread referred to at 2001-09-23 18:30
