I got regular lines in the syslog of my tinderbox like: [ 1024.289132] process 'clozurecl-1.13/work/ccl/lx86cl64' started with executable stack [ 1603.167952] __vm_enough_memory: pid: 28608, comm: pixbuf-fail, bytes: 2399126175744 not enough memory for the allocation [ 1603.167961] __vm_enough_memory: pid: 28608, comm: pixbuf-fail, bytes: 2399125123072 not enough memory for the allocation [ 1603.167965] __vm_enough_memory: pid: 28608, comm: pixbuf-fail, bytes: 2399126306816 not enough memory for the allocation [ 1603.317194] mmap: pixbuf-randomly (28633): VmData 651784192 exceed data ulimit 104857600.

Whilst the emerge itself works I do wonder about those numbers.
