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:
https://bugs.winehq.org/show_bug.cgi?id=41637
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:
