Sorry for entering into discussion late.

This is what Math::Pari is using for many years now:

   INIT_JMP_off;
   INIT_SIG_off;
   /* These guys are new in 2.0. */
   init_defaults(1);
#ifndef NO_HIGHLEVEL_PARI
   pari_addfunctions(&pari_modules,
   functions_highlevel,helpmessages_highlevel);
   init_graph();
#endif

   primelimit = SvIV(pri);
   parisize = SvIV(mem);
   init(parisize, primelimit); /* Default: take four million bytes of
			        * memory for the stack,   calculate
				* primes up to 500000. */

[Current version is a little bit different, since it tries to reinit()
PARI on the second call - not very successfully...]

Hope this helps,
Ilya
