5123	Interprocess: permissions are changed when opening a memory segment	xavi@…	Ion Gaztañaga	"In linux, fchmod is used to set the permissions after successfully shm_opening a segment. 
This is good to circumvent the problems caused by umask, but there is an error and fchmod is also run when opening (as opposed to creating) the segment, which means that opening a segment always resets its permissions to the defaults.

This can be easily fixed by changing, in shared_memory_object.hpp, the line
   
    if(m_handle >= 0)

right before the fchmod with:

    if(m_handle >= 0 && type != detail::DoOpen)
