bors-servo fdb1e511bd Auto merge of #12637 - asajeffrey:constellation-use-reentrant-logging-mutex, r=emilio ... Replaced mutex in constellation logging by a reentrant mutex. <!-- Please describe your changes on the following line: --> The double-panic in #12553 may be caused by using a non-reentrant lock, which panics on reetry. This PR adds a reentrant lock type (slightly annoyingly, the implementation in std isn't exported) and uses it for logging. cc @jdm --- <!-- Thank you for contributing to Servo! Please replace each `[ ]` by `[X]` when the step is complete, and replace `__` with appropriate data: --> - [X] `./mach build -d` does not report any errors - [X] `./mach test-tidy` does not report any errors - [X] These changes fix #12619. - [X] These changes do not require tests because they are designed to remove a class of intermittents. <!-- Pull requests that do not address these steps are welcome, but they will require additional verification as part of the review process. --> <!-- Reviewable:start --> --- This change is [<img src="https://reviewable.io/review_button.svg" height="34" align="absmiddle" alt="Reviewable"/>](https://reviewable.io/reviews/servo/servo/12637) <!-- Reviewable:end -->		2016-07-29 12:49:08 -05:00
