NAME
       function::ustack - Return address at given depth of user stack backtrace


SYNOPSIS
           ustack:long(n:long)


ARGUMENTS
       n
           number of levels to descend in the stack.


DESCRIPTION
       Performs a simple (user space) backtrace, and returns the element at the specified position. The results
       of the backtrace itself are cached, so that the backtrace computation is performed at most once no matter
       how many times ustack is called, or in what order.
