On require, Ruby stops thread scheduling and probably GC until the end
of require.  So, that's normal.

If p.rb is a personal config file, whatever occurred is writers sake :-)
If p.rb is required by several people or distributed via network,
better not just require it and develop more secure and robust scheme.
