i have this code:
https://github.com/yannick/vibed-crash-example
more or less i want to check if a redirect happened and then asynchronously send of some log information.

i open a couple of terminals and do:

while true; do curl localhost:9090/a -L; done

after a while it always crashes, report see below.

also unclear: how can i safely shutdown the Task process e.g. when
SIGINT/SIGABRT is received?

above was DMD64 D Compiler v2.068-devel-4819d48

i can reproduce it under archlinux with dmd v2.067, but not with ldc.
