| //! |
| //! This annotation will be used to confirm the theory that certain crashes are |
| //! caused by systems at or near their file descriptor table size limits. |
| //! |
| //! The format of the annotation is four comma-separated values: the system-wide |
| //! `kern.num_files` and `kern.maxfiles` values from `sysctl()`, and the |
| //! process-specific current and maximum file descriptor limits from |
| //! `getrlimit(RLIMIT_NOFILE, …)`. |
| //! |
| //! See https://crashpad.chromium.org/bug/180. |
| //! |
| //! TODO(mark): Remove this annotation after sufficient data has been collected |
| //! for analysis. |
