top: whack insidious bug surrounding auto-sized fields
This commit duplicates a change to that newlib branch.
However, it should be noted that such a change was not
really necessary under this master branch since proc_t
data remains valid much longer. It is being duplicated
here as documentation only. Below is the original msg.
------------------------------------------------------
This patch will eliminate a bug which is unique to our
newlib branch. It's extremely rare and only happens if
a search ('L'/'&') is initiated during the period when
fields are currently being auto-sized (AUTOX_MODE on).
This bug surfaces as either all zero results for tasks
displayed or a segmentation fault, depending upon what
fields were activated. It is caused by the timing of a
call to the <pids> 'reset' function. When called after
a task refresh, but before do_key(), this bug appears.
So this patch just ensures that 'reset' will be called
after do_key() & before the tasks have been refreshed.
