use 127.0.0.1 instead of localhost for testcurl/*.c;

 performs far better on OS X and Solaris-style kernels

It has truss, and for the record, it showed no slow calls.

The problem turned out to be the tests using "localhost", which was picking the primary interface for the box, not the loopback interface.

Changing perf_get_concurrent.c to use 127.0.0.1 makes it vastly faster - it went from ~35 requests/sec to 12,000-15,000 requests/sec.

It makes a big difference on OS X too - from 115-140 requests/sec on my old macbook to 600-3600 requests/sec (variation here mainly due to the large amount of other stuff I have running).

Patch attached.
