   * backend_forkexec -- fork/exec off a backend process
   *
+  * Some operating systems (WIN32) don't have fork() so we have to simulate
+  * it by storing parameters that need to be passed to the child and
+  * then create a new child process.
+  *
   * returns the pid of the fork/exec'd process, or -1 on failure
