Rack usage

How many Racks is it reasonable to have in a call stak?
Rack is such a good thing.
It is tempting to run a process with more than ten/twenty/th…
Is there a point where there could be:

  • a perfomance hit?
  • some sort of context switch issue?
  • out of memory issue?
  • debugging difficulties due to large tracebacks?
  • something else?

All.best!
