If this behavior (ignore with warning one or more Ctrl-Z keypresses during loops before eventually backgrounding) was desirable, there may be code that could be borrowed from IGNOREEOF handling (I haven't looked at it).

Thanks for your reply.  I am glad to hear that this is already on the wish list,
although I appreciate it is not straightforward to implement.

A stopgap might be to make Ctrl-Z do nothing when the currently running command is a loop or other flow control construct.
Instead it would print a message explaining that only the current subprocess would be interrupted, and saying to hit Ctrl-Z again if that is what you really wanted.  I hope this might go some way to making things less confusing, and be relatively quick to hack up.
