One thing that's different on the buildds to running the testsuite as a user is the use of fakeroot, but fakeroot doesn't intercept connect or read as far as I can see.
I looked at connect, and libc seems to just have a thin wrapper around the corresponding syscall (and indeed libc never explicitly assigns ECHILD to errno). In the kernel, the possible control flows seem quite complex, but I couldn't see where ECHILD might come from.
