Bug#498485: why: calls cpulimit with wrong arguments

[Timo Juhani Lindfors <timo.lindfors@iki.fi>]

Package: why
Version: 1.13-1
Severity: normal

calldp.ml calls cpulimit with

let cmd = sprintf "cpulimit %d %s > %s 2>&1" timeout cmd out in

but the cpulimit tool in debian expects different syntax:

$ cpulimit
Error: You must specify a target process
Usage: cpulimit TARGET [OPTIONS...]
   TARGET must be exactly one of these:
      -p, --pid=N        pid of the process
      -e, --exe=FILE     name of the executable program file
      -P, --path=PATH    absolute path name of the executable program file
   OPTIONS
      -l, --limit=N      percentage of cpu allowed from 0 to 100 (mandatory)
      -v, --verbose      show control statistics
      -z, --lazy         exit if there is no suitable target process, or if it dies
      -h, --help         display this help and exit


tools/cpulimit.c has an alternative cpulimit that has

fprintf(stderr,"usage: %s <time limit in seconds> <command>\n",argv[0]);

as the syntax.
