Description of problem:

In previous versions of curl (7.16.1-3.fc7), the current status, seen when
curl is run with no extra arguments, was updated at an interval of about
1 second. This was good. However, the updated curl (curl-7.16.2-1.fc7)
refreshes the status without any let-up, as much as console takes it.
This is wasteful and causes ripple effects across the desktop whenever
a download is running (e.g. fans kick up).

Version-Release number of selected component (if applicable):

curl-7.16.2-1.fc7

How reproducible:

100%

Steps to Reproduce:
1. Run curl in a poorly performing terminal emulator, like gnome-terminal
2. Observe that cursor runs like crazy all over the status line
3. Observe (with top) that the emulator and X server start eating CPU

Actual results:

Wasteful system load

Expected results:

Working as before

Additional info:

I think someone passed some wrong argument to some timer call.

I understand that I can kill status with a command line argument, so
no big deal, but this clearly is a regression, hence the bug report.
