# SO_RCVTIMEO socket options for this to work. So we will check
# if this feature is supported by a simple TRY_RUN macro. However
# on some OS's there is support for setting those variables but
# they are silently ignored. For those OS's we will not attempt
# to use SO_SNDTIMEO and SO_RCVTIMEO even if it is said to work.

# Solaris11 has a similar problem
