I used the trick of vi called at every launch, storing the refences on an array in a shift register of a one shot while loop. I can store or read the refences.
But i am vexed for the impossibility to trace the references of the reentrant copy of the vi in the same way that it's possible for the non reentrant.
I see that the "profile vi" tools does not report nothing about the vi launched trough the vi server method. 😞
