option 1. Use select() to tell you if there is anything to read and when you can write, if the connection drops then you will be told you can read something and will then get the appropriate error returned by "recv", only "send" if select tells you can write.
option 2. install a SIGPIPE signal handler around the send() to catch any raised signal, then restore the handler after the send.

net.recv
Net.recv(3kaya) Kaya module reference Net.recv(3kaya)
NAME
Net::recv - Recieve data from a connection.
SYNOPSIS
String recv( NetHandle h, Int maxlen=-1, Int timeout=0 )
ARGUMENTS
h The connection
maxlen The maximum number of bytes to read (or unlimited, if negative). For TLS connections, this is always unlimited. Note that if the
data to be received contains multi-byte characters, care must be taken to avoid ending receiving part-way through a multi-byte character.
timeout The number of seconds to wait without input before timing out. The default is zero. For TLS connections, this parameter is ignored.
DESCRIPTION
Reads up to maxlen bytes from the connection, and times out after timeout seconds.
