New description:
The following is a non-reproducible problem, but it happened several
times.
When building the Sage documentation using
{{{
make doc-html
}}}
it can happen that {{{make}}} simply hangs forever after the message
{{{
Build finished. The built documents can be found in
/mnt/usb1/scratch/jdemeyer/merger/sage-4.6.1.alpha0/devel/sage/doc/output/html/fr/a_tour_of_sage
}}}
Pressing CTRL-C at this point gives
{{{
make: *** [doc-html] Interrupt
}}}
Here is a `ps` snapshot of a situation where it happened:
{{{
$ ps -u jdemeyer xfo pid,ppid,sess,tty,tpgid,args # Irrelevant entries
removed

Note the orphaned `sage-cleaner` process with the same session ID as `make
doc-html`.
