The version I'm building against for node.js 0.10.12 is libuv 0.10.11. I
should probably mention that when I said I was getting
EINPROGRESS back, I was being inaccurate - I was getting -1 back as the
status, and the errno was EINPROGRESS. I've since tried building
against libuv 0.10.12, and I do indeed get EBADF back in the status instead
of just -1.

It does (well, except for the TCP/IP v6 cases, but that's not a big deal).
I should mention that I'm running all this on a Raspberry Pi
running the latest version of Raspbian. I'm building against BlueZ version
5.7 as well.
Last, do you have a small test case which reproduces this?

I do. You'll need BlueZ headers and libraries installed to make it build.
I've attached the C++ test file.
Here's how I'm building it:
$ c++ -g -fpermissive -I/home/pi/.node-gyp/0.10.12/deps/uv/include/
-lbluetooth -lpthread -lrt -o test test.cc ../libuv/out/Debug/libuv.a
I went ahead and built it on my pi against libuv 0.10.12,
which gave me the following output when I ran it:
$ ./test
connect returned -1, errno = 115
onConnect called, status = -9
Thanks for your help!
