 So that it can be run while the program is generating the profiling data.

 Anyone who would reimplement hp2ps (e.g. #3024) would probably fix this
 along, but still this is an issue on its own, hence I’m opening a separate
 ticket.

 If someone feels like hacking on it, beware: hp2ps is written in C.
