Running it as root, you will notice it says it's Reusing existing ksycoca, I think (as root) it's trying to kill kbuildksycoca (which is needed by other running kde programs) when you quit kcron.
Mutexes are there to stop races within a program when multiple accesses occur.... (snip)
I got intrigued. The topic had come up before in January: http://lists.suse.com/archive/suse-linux-e/2004-Jan/2133.html where Jerry Feldman gave a similar explaination to Sid's. I did a search at google.com/linux, and it returned an IBM article: "Basic use of pthreads," by Peter Seebach. Peter gave an origin of term Mutex: A mutex is short for MUTual EXclusion. and said, it is a way of keeping pthreads from stepping on each other. I found the article interesting: http://www-106.ibm.com/developerworks/linux/library/l-pthred.html?ca=dgr-lnx... When I was learning Fortan in the '60, nobody told me about pthreads or mutexes.
