Comment:
If I evaluate
{{{
#!python
print 'Hello!'
plot(sin(x))
}}}
then "Delete All Output," "Save & quit" and reopen the worksheet, the plot
(not the text) reappears.
We could also delete the cells' files in `Worksheet.delete_all_output`.
But we may wish to do this synchronously; otherwise, a long-running or
simply delayed (e.g., on a busy server) thread might remove newly-written
files.
(For deleting just one cell, there might be a similar but less likely race
condition. For example, if after deleting a cell (with ID <id>) in the
browser, a user pastes and saves `{{{id=<id>|\n<updated code>///\n\n}}}`
in the "Edit" window, and re-evaluates the cell, a delayed `Deferred`
could delete new files.)
What do most users expect/prefer?
I'm adding `schilly` to the Cc: list, since he's almost certainly better
qualified than I on this (and many other) topics.
