Comment (by joeyhess):

 prctl can be used to set the name of a thread. This does not change the
 process name as displayed by ps. (The stackoverflow article is apparently
 wrong or out of date or something -- try the sample program there and
 you'll see it does not change the display in ps, although
 /proc/pid/task/tid/comm will be changed.)

 At least on linux when using libbsd's setproctitle, it requires
 setproctitle_init to first be called and passed the original argv. The
 libbsd-ctor arranges for this to be done at program startup. So, I was
 able to get that to work by passing these options to ghc: -lbsd-ctor
 -optl-u -optllibbsd_init_func -lbsd

 On linux, using a not very widely used libbsd, and needing linker options
 to make it work, seems like a rather long way around..
