Comment (by Kronuz):

 I've added a reproducer which shows the socket leak. It implements the
 most basic server which throws an exception after client opens the
 connection.

 Run as `c++ -std=c++14 -o tst-xapian_remote -lxapian tst-xapian_remote.cc
 && ./tst-xapian_remote`, after a while, you'll start receiving
 `NetworkError: Couldn't connect (context: remote:tcp(localhost:5000))
 (Can't assign requested address)`, when there are no longer any file
 descriptors available.
