Comment 12 for bug 1303649

The problem here is that applications linked to the cgmanager client library are not calling nih_main_loop(). That's a problem because the nih-dbus code calls nih_main_loop_interrupt() which adds a byte to the main loop interrupt pipe. After 65536 bytes have been added to that pipe, the next call to nih_main_loop_interrupt() will result in the repeated EAGAIN shown above.

The correct solution is for the clients to use an nih main loop.
