Description:

When VMA_HANDLE_SIGINTR=0, the following issues are no longer encountered:
1. When SIGNIT is caught by VMA, subsequent calls to socket API return EINTR error code immediately.
2. VMA_HANDLE_SIGINTR parameter is ignored by signal() API.

However, when VMA_HANDLE_SIGINTR=1, only the first issue persists.
