I don't think so.  I scanned the code for res_init() and nothing
appears to allocate any sort of resources:

  http://darwinsource.opendarwin.org/10.4.2/Libinfo-221/dns.subproj/res_init.c

A test of a tight loop ("while(1){res_init();}") shows no growth in
memory consumption and no errors/crashes/etc.

No.
