Description

After this hit me initially on a regular make check, I did run the test isolated in infinite repetition - those 3 times I tried it, the bug surfaced at around 100-150 repetitions.

$ ./3rdparty/libprocess/libprocess-tests --gtest_filter="ProcessRemoteLinkTest.RemoteLinkLeak" --gtest_repeat=-1 --gtest_break_on_failure

Repeating all tests (iteration 119) . . .

Note: Google Test filter = ProcessRemoteLinkTest.RemoteLinkLeak
