SubjectQuestion on /proc/interrupts

Short question on /proc/interrupts.

If I do a "cat /proc/interrupts" I get:

0: 2747188 XT PIC timer
1: 12958 XT PIC keyboard
2: 0 XT PIC cascade
4: 288563 XT PIC serial
8: 0 XT PIC rtc
9: 45153 XT PIC ncr53c8xx
13: 1 XT PIC fpu

Assuming that this is a counter of interrupts happened so far, I am
wondering, why the counter for the fpu-interrupts still is "1", even
if I have done such heavy calculating stuff like rendering or raytracing
(bmrt/povray). MATH_EMULATION of the kernel is switched off, I am
using a AMD K6.

What happens here?
