Description Roland McGrath 2012-10-19 18:36:40 UTC
Just using clock_gettime in a dynamically linked program requires -lrt.
librt.so depends on libpthread.so, so such programs wind up loading libpthread even if they have no need for it.  This enables libstdc++ locking code and the like, slowing down single-threaded programs that only wanted clock_* calls.

Implemented.  Cannot be backported.
