    I think I did it "defensively" when debugging problems in the
sagemath package, as newer pari uses a lot of tls variables, e.g.

$ grep -r __thread .
./src/headers/parisys.h:#  define THREAD __thread

$ grep -r THREAD . | wc -l

and it has things like __thread static variables in functions, several
global variables, etc.

  But at least in pari 2.5.1 it is disabled by default.
