Subject: Using to_io with Marshall.dump

Hi, Ruby Marshal.dump allows writing directly into a IO object:
dump( obj [, anIO] , limit=--1 ) → anIO
Serializes obj and all descendant objects. If anIO is specified, the
serialized data will be written to it, otherwise the data will be returned
as a String.
However it doesn't work with POSIX_MQ#to_io:
Marshal.dump msg, posix_mq.to_io
=> ERROR: Errno::EINVAL: #<Errno::EINVAL: Invalid argument> (in `write')
Is it not possible or do I miss something?
Thanks a lot.
