In most cases, if it takes a while it is filename completion trying to
look for files in the full path: the stuff which allows /u/l/b to
complete to /usr/local/bin.

It depends what you are trying to do. Are you trying to show the
completers or the zstyle context? _main_complete is not the only place
the context is changed so for showing the context, _description or
_setup would be a better place.

Why not just stick $SECONDS (as floating point) in PS4 and use

I'm not convinced we should be sticking debug stuff like this into
completion unless it really is proven to be useful. I normally prefer to
use a second tty for completion debug output instead of zle. And it
isn't hard to make temporary changes to _main_complete (or whatever) for

Either you have to replace compadd with a function or, depending on
where you produce the debug, you might be able to check
