Sudo does set the limits for the target user just before the program
being run under sudo is executed if PAM is configured to use
pam_limits.so as part of the PAM session.  It sounds like the problem
is ocurring long before then, though.

I suppose sudo could stash the current resource limits and set them
to the max as part of its startup, potentially restoring them later.
