Comment 71 for bug 1567540

Harlan, the repo is in

  psp.ntp.org:~perlinger/ntp-stable-2831

compiled and run with

  linux/x64 --with-threads (threading resolver)
  linux/x64 --without-threads (forking resolver)
  Windows7/x64/VS2008 (threading resolver)

Hal, Mike, good catch. Only the proposed lock falls a bit short. You have to interlock all access to the global table, not just the realloc() call.

And using pthread_mutex_t is not so easy with Windows, but we all knew that ;) I used a semaphore (again) since there is already a suitable wrapper.
