/**
* Prints critical warning if process exists in /proc/ directory and is not

* @param proc an #u_proc
*
* \note
* If DEVELOP_MODE defined, this assertion is called everytime some process
* is marked as dead, specifically on each U_PROC_STATE(P, UPROC_VANISHED) or
* U_PROC_STATE(P, UPROC_ZOMBIE) macro call. Assertion failure in this case is
* a symptom that ulatencyd core is making false assumptions about /proc/<pid>/
* files behaviour, i.e. it falsely assumes some process disappeared or is
* a zombie, instead it is still alive.
