Would it be best to use 1.4.4 specifically, or simply the most recent
1.4.x (which appears to be 1.4.5 at this point)?

I'm happy to provide, but what exactly are you looking for? The test code
I'm running is *very* simple:
main(int argc, char **argv)
int i, j;
printf("Hello World from Node %d.\n", node);
for(i=0; i<=1000000000000; i++)
And my environment is a pretty standard CentOS-6.2 install.
