During Shiva, a mourner is allowed to study Sefer Iyov. Assuming that learning this one sefer is enough to make a siyum, could a mourner make a siyum during the shiva to mark his completion of what he was allowed to do?
Here is one implication -- if, for example, the shiva overlapped the 9 days, could the mourner (and, OR, anyone making a shiva call) then eat meat?
Once one is allowed to study Torah (all the moreso, a daf of gemara that deals with mourning and which, according to the linked answer, be enough to justify a siyum for a non-learned person) can one mark the completion of that study. Does the mourner have to wait until the end of shloshim and make his siyum well after finishing learning?
