Extensions timeout

[Mirek Lauš]

I’m still getting extension timeouts, nodeJS process exits due
to signal 6, leaving a coredump behind:

> (gdb) core node.core
> Core was generated by `/usr/local/bin/node lib/extension-wrapper remote'.
> Program terminated with signal 6, Aborted.
> #0  0x0000000804b3447a in ?? ()

How to tell what’s going on?
