Note that to OTA-7 we fixed one stale process lock files bug #1500444.
That was the 2015-05-26 commit from http://code.qt.io/cgit/qt/qtbase.git/log/src/corelib/io/qlockfile_unix.cpp
The only other patch that could sound worthwhile would be the syncing-to-disk commit http://code.qt.io/cgit/qt/qtbase.git/commit/src/corelib/io/qlockfile_unix.cpp?id=4accd865c24b7ed918cb705913478bab5aeb5e6e , and it does state "to avoid leaving an empty lock file on crash".. maybe on kill too? https://bugreports.qt.io/browse/QTBUG-44771
