Bug description:
  If you have no stack limit (ulimit -S -s unlimited), any pgrep call
  will fail with an error:

  > pgrep vim
  pgrep: cannot allocate 4611686018427387903 bytes

  If you have a high stack limit (e.g. ulimit -S -s 500000), pgrep is
  very slow:

  > time pgrep vim
  2196
  real 8.48s user 8.40s syst 0.07s busy 99% rmem 253444
