Comment #4 on issue 253 by [email protected]: Correctly handle the symbolizer pipe on fork()
http://code.google.com/p/address-sanitizer/issues/detail?id=253

Instead of a pipe you can use a SOCK_SEQPACKET socket to communicate between the symbolizer and the parent process. Then the child processes can simply use the same fd.

I know you can do many-to-one communication in this way, but I'm not sure about one-to-many. I think it's possible with sendto(). Will have to check.
