Comment (by rhaas):

 I put it in a thorn since every other external library is also in a thorn.
 Specifically I also have a thorn to link against Intel's trace analyzer.
 Currently the feature is provided by the flesh (via the extras directory
 in lib/make) using PTHREADS=yes which is the single last remaining user of
 those features. There is no code since we cannot build our own pthreads
 since they required kernel support and there seems to be no userland
 library that could be used in multiple OS in the case we encounter an
 system (workstation?) where the kernel provides thread support but the
 userland libraries are missing (like PAPI).
