What is the function of textConnection here? Is read.table
incompatible with socketConnection for some reason?

This is not a problem in itself. For some reason, R gives a warning
when connections are garbage collected. Of course, that can be a
symptom of poor connection management, but not necessarily.
In the present case, you are creating many unnecessary
textConnections, and R correctly garbage collects them.
