As a side note, I attempted to debug the issue using strace by tracing the connect system call with the command:
$ strace -e connect python ./t1.py
connect(3, {sa_family=AF_INET, sin_port=htons(8008), sin_addr=inet_addr("XXX.XXX.XXX.XXX")}, 16) = -1 EINPROGRESS (Operation now in progress)
connect(3, {sa_family=AF_INET, sin_port=htons(8015), sin_addr=inet_addr("XXX.XXX.XXX.XXX")}, 16) = -1 EINPROGRESS (Operation now in progress)
