----------------------------------------------------+-----------------------
 When a filtering_stream with a gzip_compressor is used to write to a full
 hard drive (i.e. insufficient free space), boost enters an infinite loop
 in /boost/iostreams/detail/adapter/non_blocking_adapter.hpp:41 because the
 write function keeps returning zero. This loop happens during the
 destruction of the stream. I can't seem to find a client-side workaround.

 Attached is a test case, point it to a volume with zero space and give
 some large number of bytes. If there's insufficient space, execution
 hangs. Tested on mingw/winxp/gcc4.2 but seems to fail on linux/gcc as
 well.
