Bug description:
  A few kernels updates ago (after kernel 3.13.0-98) on 14.04 (Trusty) a
  backported fix for Dirty COW from kernel 4.8.3 resulted in some Delphi
  apps freezing wineserver and leaving it unkillable:

  I haven't tested for the bug on 16.04 Xenial (kernel 4.4.0-59) but it
  is probably affected.  A patch is available:
