I've updated code and documentation at  
<http://www.highscore.de/boost/process0.5/>:

- On POSIX set_on_error and throw_on_error report now if execve() failed  
in the forked process.
- return_on_error has been removed.
- set_env has been added to make it possible to set environment variables.
- close_fds_except has been changed to close_fds_if (it expects now a  
predicate).
- The executors call now also an initializer function after a system call  
returned successfully.

More changes to come.
