The context:

I am trying to control a mobile robot from squeak.  I wrote the code for
squeak 2.3 and I'm updating it for 2.6.  The mobile robot (or the
simulator) receive commands via sockets with a command/reply type
protocol.  This code tries to read the robot's reply after sending a
command.  The socket does not close.  When the error notifier comes up,
I open the debugger and inspect the value of 'read' and find that it is
zero.  I can then manually do a "socket receiveDataInto: buffer" and the
data is read, or I can restart the method and everything continues
working until a while later, when the error notifier comes up again.

I am connecting to a robot simulator running on the same computer as the
squeak system.

Thanks for your help,
						Juan.
