A couple of weeks ago, TLS connections started making Emacs hang.  I've
yet to find a way to reproduce it reliably, but it seems to involve
opening an async TLS connection while opening a synchronous TLS
connection, or something.

strace in these instances shows an infinite loop like this:

[pid 28250] pselect6(27, [4 6 8 9 10 14 15 16 17 18 19 20 22 24 26], [], NULL, {0, 0}, {NULL, 8}) = 1 (in [20], left {0, 0})
[pid 28250] pselect6(27, [4 6 8 9 10 14 15 16 17 18 19 20 22 24 26], [], NULL, {0, 0}, {NULL, 8}) = 1 (in [20], left {0, 0})
[pid 28250] pselect6(27, [4 6 8 9 10 14 15 16 17 18 19 20 22 24 26], [], NULL, {0, 0}, {NULL, 8}) = 1 (in [20], left {0, 0})
[pid 28250] pselect6(27, [4 6 8 9 10 14 15 16 17 18 19 20 22 24 26], [], NULL, {0, 0}, {NULL, 8}) = 1 (in [20], left {0, 0})

Does this ring a bell?  If not, I'll try to debug it further.

I think it started happening like two or three weeks ago.
