openssh unix dev - Aug 2008 - dynamic allocation in bsd-poll.c?

I'm wondering about the rationale behind the allocation of the fd_set
for the select() call in bsd-poll.c.

Is there a reason we're dynamically allocating the fd_sets using nmemb,
rather than simply putting three fd_set variables on the stack, followed
by FD_ZERO calls?

This seems to make life more difficult, as evidenced by the "goto out"
statement, needed to free the memory.
