That is weird, but maybe it is not a deadlock, but a very slow progress. In the
child can you print the fdmax and i in the frame do_child.

Jeff, thanks.
from 1:
(lldb) process attach --pid 95083
Process 95083 stopped
* thread #1, queue = 'com.apple.main-thread', stop reason = signal SIGSTOP
frame #0: 0x0001bde25628 libsystem_kernel.dylib`close + 8
libsystem_kernel.dylib`close:
-> 0x1bde25628 <+8>: b.lo 0x1bde25648
You can use "lldb -p PID" to attach to a running process.
