Another hang. This time sending was not involved, The only two
activities were refreshing an account (i.e. a background action) while
trying to read a message from the same account. A trace was been
uploaded to BZ, and once more the strace info is an unending stream of:

poll([{fd=3, events=POLLIN|POLLOUT}], 1, -1) = 1 ([{fd=3, revents=POLLOUT}])
writev(3, [{iov_base="&-\2\0006\0\0\2", iov_len=8}, {iov_base=NULL, iov_len=0}, {iov_base="", iov_len=0}], 3) 
= 8
poll([{fd=3, events=POLLIN}], 1, -1)    = 1 ([{fd=3, revents=POLLIN}])
recvmsg(3, {msg_name=NULL, msg_namelen=0,

recvmsg(3, {msg_namelen=0}, 0)          = -1 EAGAIN (Resource temporarily unavailable)
etc.

[As an aside, it's especially annoying when Evo takes so long to
respond when the user explicitly decides to quit during these events.
Is there a way of changing the default timeout? Just killing all Evo
processes and restarting is much faster and has never once had a
negative effect in all my years of using it.]
