STINNER Victor added the comment:

The testFDPassSimple pass: it's possible to pass a file descriptor between two \
processes. Hum. The testMultipleFDPass test also pass: it's possible to pass multiple \
file descriptors. Both tests use SCM_RIGHTS. The testCMSG_SPACE test also pass.

It looks like the difference between testMultipleFDPass and testFDPassSeparate is the \
number of "cmsgs" ("access ancillary data"): 1 cmsg for testMultipleFDPass, two for \
testFDPassSeparate.

I don't understand if it is a bug in the Python socket.sendmsg() function serializing \
ancillary data, or "just" if the AIX kernel does not support multiple ancillary data \
for sendmsg().

@David: any idea? Did you ask IBM?
