[filedesc->readobject] reads an object with no timeout.

When a new thread is created by calling [capture->splitThread], the return value of that method call is a pair of [filedesc] objects. Similarly, the parameter given to the new thread is a pair of [filedesc] objects. A [filedesc] object represents a file or pipe over which data can be sent or received. These [filedesc] objects provide a means for the new thread and the creator thread to communicate. Two [filedesc] objects are required for thread communication, one representing the write end of the pipe and the other representing the read end. Objects are written to the write filedesc and read from the read filedesc.
