Here is the next (minor) update of the library (ZIP file updated at  
<http://www.highscore.de/boost/gsoc2010/process.zip>; changes in  
Subversion at <http://svn.boost.org/svn/boost/sandbox/SOC/2010/process/>).

What has been changed?

* The constructor of boost::process::handle supports an optional parameter  
to specify whether a handle should be automatically closed (by default the  
handle is closed). boost::process::behavior::inherit passes "dont_close"  
to the constructor to avoid that a handle inherited by a child process is  
closed by the parent process (as the handle is inherited it is a handle in  
use by the parent process and must not be closed). The function  
boost::process::create_child() does not explicitly close handles anymore  
but simply lets them go out of scope.

* The stream behaviors don't return a std::pair<handle, handle> anymore.  
There is now a new struct called boost::process::stream_ends which has two  
member variables child and parent. Now there is no need anymore to  
remember whether first or second was the child's end.

I'd appreciate if you could comment on the changes. Especially have a look  
at:

* the enumeration close_type in boost::process::handle (see  
<http://svn.boost.org/svn/boost/sandbox/SOC/2010/process/boost/process/handle.hpp>).  
Is there a better name for the enumeration? Are there better names for the  
values in the enumeration? I don't like "do_close" but then the name  
"close" is already used at too many other places.

As this is a minor update there will be some more changes soon (hopefully  
this weekend).
