From: Mark T Date: 2010-11-05T12:15:35+09:00 Subject: 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!
