Same for me and interestingly:

Every process gets a standard input, output, and error file descriptor.
Other exist only if they're opened. These are process-specific.
What's mysterious about the reported case is that the 3<< ... did not
seem to create a /dev/fd/3, at least not at the right "time" ...
