1 zombie process after starting a 23 bit UML guest

Today I realized that current kernels produces a zombie proces :

tfoerste@n22 ~ $ ps aux | grep 'Z' | grep '<defunct'
tfoerste 10918 0.0 0.0 0 0 ? Zs 23:11 0:00 [linux-v3.12-48-] <defunct>

The last kernel which does not produce such a zombie is kernel 3.11

I do not use a xterm for any output, just "con0=fd:0,fd:1 con=pts". However I'm unsure if this is an already known issue (and I just forgot it) or whether I should kick my test box to bisect the guelty commit id between 3.11 and 3.12

My mistake,

the zombie process is created, if I start the UML just as a back ground process. If I prepend my command line with "nohup" in such a case then a zombie process isn't made.
