Tricky. I think that we saw the following sequence:
stop osd N
export pg X at epoch e
split pg X at epoch e+3
osd M receives pg X', child of X at epoch e+5
restart osd N
stop osd M
import pg X at epoch e
restart osd M
split pg X at epoch e+3 into X'
filestore crash EEXIST, X' already exists

Not precisely sure how to approach this. We can make the OSD robust to this situation or we can adjust the test to avoid it.
