Hi,
I noticed a problem of gnunet-download with SVN 5643 (2007-09-18).
Doesn't react to Ctrl+C even after a day or so of running. Attached GDB
and did backtraces on all threads, see gdb.txt (attached).
One thread waits on another to quit via 'pthread_join'. Other thread
waits on some mutex... looks like a deadlock.
Although I played quite a lot with gnunet-download, this only happened
once so far.
regards,
David

The program is running. Quit anyway (and detach it)? (y or n) Detaching from
program: /usr/local/bin/gnunet-download, process 5028
