Review comments at @jemalloc-ctl/src/thread.rs:
- Around line 113-114: The tcache_enabled option! invocation omits required
macro arguments and fails to compile; add the MIB type identifier and test
identifier required by option!, following the naming pattern for neighboring
options while preserving its existing string, non-string, and operation
arguments.
