(Win32 only) Assertion failed: Address already in use (..\..\..\src\signaler.cpp:80)

[mato]

When running an application which uses lots of sockets on Win32, I get this assertion.

This appears to be caused by a WSAEADDRINUSE return from connect () on the emulated socketpair used by signaler_t.

MSDN docs at http://msdn.microsoft.com/en-us/library/ms740668%28VS.85%29.aspx suggest using SO_REUSEADDR but this doesn't seem to help. It's not clear if this is just Winsock running out of "ports to assign to sockets", or something else.

I guess the best solution in the long term is to migrate to IOCP on Win32 which should let us use Named Pipes or some other IPC mechanism for the signaler.

On Windows Server 2008 you have SO_PORT_SCALABILITY to avoid this problem.
