+Subject: [PATCH 3/3] process: Fix gettid() ambiguity with glibc >= 2.30
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+In version 2.30 glibc added it's own gettid() function. This resulted in
+"error: call of overloaded ‘gettid()’ is ambiguous" because gettid()
+now exists in both namespace crucible and std.
+
+For now, use explicit references to namespace crucible.  This continues
+to work with new and old libc without having to test specific library
+versions.
+
+At some point, glibc gettid() will be deployed widely enough that we can
+remove the crucible version entirely.
