Releases a resources previously allocated by g_cancellable_get_fd()
or g_cancellable_make_pollfd().
For compatibility reasons with older releases, calling this function
is not strictly required, the resources will be automatically freed
when the @cancellable is finalized. However, the @cancellable will
block scarce file descriptors until it is finalized if this function
is not called. This can cause the application to run out of file
descriptors when many #GCancellables are used at the same time.
