The same exportfs runs on A and B.
B->A woks, A->B doesnt.
Probably there is something wrong on A, not in exportfs.
Not a "true" bug but a not-well-managed (because very-very strange)
external event/condition.

I'll investigate with some print() in the code, I don't know how to use
acid on an exportfs started by listen.
