This appears to have been fixed in the 5.8 track. With 5.8.6 I can ctrl-c at the accept() call and I am dumped into the debugger at the proper place. With 5.5.4 it didn't respond to ctrl-c at all, I wasn't dumped into the debugger nor did the process exit. So I'm reasonably sure this is resolved. Please let us know if it is not.
