[E-devel] Ecore_con_dns patch

[Joel Klinghed]

Hi.

Attached is a small patch for Ecore DNS lookup.

When forking all queued atexits is copied as well.
This creates trouble in at least embrace, or rather Edb when the forked
dns lookup calls exit.
So, changed to a exit function that doesn't call all queued atexits.
Only tested with GNU libc.

Symptoms:
The forked children of embrace takes 100% CPU and (naturally) hogs the
system.
Have attached a backtrace after interrupting one of these children.
Only embrace was compiled with debug symbols.

Regards, Joel Klinghed
