#9616: segfault / NFS problems with parallel/decorate.py
-----------------------+----------------------------------------------------
Reporter: ddrake | Owner: mvngu
Type: defect | Status: new
Priority: blocker | Milestone: sage-4.5.2
Component: doctest | Keywords: fork nfs segfault

-----------------------+----------------------------------------------------
In 4.5.2.alpha1, we have for many people:
{{{
sage -t -long "devel/sage/sage/parallel/decorate.py"
------------------------------------------------------------
Unhandled SIGSEGV: A segmentation fault occurred in Sage.
This probably occurred because a *compiled* component
of Sage has a bug in it (typically accessing invalid memory)
or is not properly wrapped with _sig_on, _sig_off.
You might want to run Sage under gdb with 'sage -gdb' to debug this.
Sage will now terminate (sorry).

This seems related to #9501.
