Dear Antoine
I compiled the ocaml library after invoking the O_UNBLOCK flag as per your original instructions.
I get a continuous red stream of "Unix.Unix_error(2,"read", "")" in the paparazzi centre console interspersed with
"File ", line362, characters 4-10:Assertion failed" in white after I click the execute button in the paparazzi centre.
It must be noted I get no build or upload errors.
I then did a "make clean make" command and the whole system just locks up.
I then removed the O_UNBLOCK flag and recompiled only to unfreeze the system but the gcs windows reappeared unpopulated. 
I have yet to retry adding the flag as it is getting late here.

just to make sure, you recompiled the ocaml library after adding the
flag to open ?
