Comment 3 for bug 1337827

So, after some browsing, it apears that trap recursion was introduced intentionally in 4.3-rc2. There is commented code in bash.c that makes it look like trap recursion was originally intended to be a configurable build option, but was made default behaviour instead.

One fairly easy fix would be to use a definable recursion limit within run_pending_traps, but I suppose we should really get a verdict on whether the plan is for recursion behaviour to stay as-is or to become a configurable option.
