Details

Bug 1739924 was a bad regression in Linux stability that manifested as a pre-existing crash (bug 1514734). It took me a while to dig into the crash stats to even notice that there was a new issue because it looked like the existing issue. Maybe if we had logging for the specific underlying cause for failure to create the shared string map it would be more obvious when something changed. There are a few different reasons it can fail. AFAICT bug 1739924 would show up as a bad file handle, whereas an OOM might show up differently. This might feel a bit like overengineering, but this chunk of code is apparently the first thing that runs during process startup that tests the limits of a few different resources.
