The change done in 2.1 include an added field for address space in the

cgi_exec_info struct.
The field could not be backported because of a requested number bump. 
This is why I need to overload the detached field from the same
structure in the 
2.0 branch, not in the 2.1. 
How could I propose a backport on changes in mod_cgi.c that will only
be in 
the 2.0 and not in the 2.1 branch? This is not a backport, the 2.0
changes
are partially a workaround in order to keep binary comp. 
Thank you,
