you could write a clarifying comment saying that it is possible to initialize
the manifest channel lazily, but it would require constructing a mutex

I don't think that we need to comment all roads not taken in the comments. I
added more reasons for eager initialization in the answer to Roland.

+  if (IRTInit()) {
+    static const char fatal_msg[] =
+        "irt initialization (IRTInit) failed.\n";
+    write(2, fatal_msg, sizeof(fatal_msg) - 1);
+    _exit(-1);
+  }
+}
