Not really: it only solves the problem *if you change the application*,
which is IMHO not acceptable. In particular, why should a non-threaded
app expect to have to change to deal with this issue? But we can't
safely build a thread-safe libpq.so for general use if it breaks
non-threaded apps that haven't been changed.
As for the efficiency argument, we have been doing two pqsignal()s per
send() for years and years; I see no reason to think this is worse.
