I really like the GP notation of "#" for "number of" in eg. 
"#binary(n)".

Given that the reader of PARI/GP doc knows that, replace

• pthread: number of threads (unlimited, default: number of cores)

with (for current implementation)

• pthread: number of threads (unlimited, default: number of hardware 
threads^1)
...
^1 = #sockets * #cores_per-socket * #threads_per_core

One could append " (as reported by lscpu under Linux)" or not.
