>Description:
'vmstat 1' shows my system making 117000 syscalls every other second.
Removing the USB mouse causes the syscall count to drop by half.
Starting the system without the USB mouse does not make the problem go
away. A syscall trace shows the program attempting to set FD_CLOEXEC
on every one of 11000 possible file descriptors before execing fstat.
fstat then proceeds to do many more syscalls as it paws through kernel
memory. This adds up to about 4% CPU usage on an otherwise idle
dual-CPU machine.
Personally, I'm not so perturbed by this, but this is obviously bad
for laptops or performance-critical situations.
I've not analyzed this further to see where all the CPU time is going,
but the amount does seem excessive for what's actually being done.
