Is this a virtual machine? 260096kB of RAM was probably not enough.
Therefore it used a lot of swap memory, which explains why the process took
so long.

*ouch* Looks like you've had no swap left, either. Probably you ran out of
memory during the commit and the process was killed by the kernel when the
process tried to allocate even more.
