  "message": "threads_posix: Use thread-local storage to cache thread ID\n\nTrying to capture debug logs that reproduce a problem can be tricky.\nTurning up the debug level will automatically make the program a bit\nslower. This alone cane make timing-sensitive bugs \"disappear\" when\ncapturing logs. One of the hot paths for debug messages is fetching the\nthread ID, which is immeasurably helpful in understanding thread\ninteractions within the library. Unfortunately most implementations\nrequire a system call to fetch the executing thread\u0027s ID, which isn\u0027t\nexactly going to help in the way of execution time.\n\nAdd a check for thread-local storage support when configuring the\nlibrary to build. If the toolchain provides this support, only one\nsystem call will be required per thread. This check is only done for\nnon-Windows systems because thread-local storage is inefficiently\nimplemented on MinGW.\n\nCloses #682\n\nSigned-off-by: Chris Dickens \u003cchristopher.a.dickens@gmail.com\u003e\n",
