> Components: Python Client

>
> The python client uses select() to wait for socket activity. select() is
> used because it is available on most platforms. However, select() has a hard
> limit on the _value_ of an file descriptor. If a socket is created that has
> a file descriptor > the value of FD_SETSIZE, the following exception is
> thrown:
> Exception in thread Thread-1:
> Traceback (most recent call last):
> File "/usr/lib64/python2.4/threading.py", line 442, in __bootstrap
> self.run()
> File "/usr/lib64/python2.4/threading.py", line 422, in run
> self.__target(*self.__args, **self.__kwargs)
> File "/usr/lib/python2.4/site-packages/qpid/selector.py", line 119, in run
> rd, wr, ex = select(self.reading, self.writing, (), timeout)
> ValueError: filedescriptor out of range in select()
> Note well: this is caused by the _value_ of the fd, not the number of open
> fds. A process that has many files open, then attempts to create a qpid
> connection, could hit this problem.
