[lwip-devel] [bug #47485] lwip_netconn_do_close_internal blocks caller during memory error

[Joel Cunningham]

Follow-up Comment #2, bug #47485 (project lwip):

The change for bug #48543 removes the requirement of having space in the send
buffer to send a FIN.  That eliminates the particular memory error case I had
encountered when trying to close a non-blocking socket with a full send
buffer.

This issue is still present if there are other memory allocation failures that
could occur during sending of the FIN (which we would need to block until they
could be resolved)
