precompile: add pid to waiting message

[IanButterworth]

See JuliaLang/julia#50914

Seems like the pid might useful for profiling what's lingering

If we decide it's actually useful to know the PID, then this would indeed be useful. Thanks!

I don't have time to play with this more today, but presumably this is easy to test. PyPlot 2.11.1 would make an easy test case, see JuliaPy/PyPlot.jl#573.

Hmm, yeah. This doesn't look too helpful in this case, which was just a Timer(30) added to the module

There doesn't seem to be benefit to doing this. Also the output will be shown live in common dev usage patterns now thanks to #3582
