[Texmacs-dev] what is texmacs constantly doing ?

Hi,

I recently looked at the output of strace and I get

....
ioctl(5, FIONREAD, [0])                 = 0
ioctl(5, FIONREAD, [0])                 = 0
gettimeofday({1205790064, 238625}, NULL) = 0
ioctl(5, FIONREAD, [0])                 = 0
ioctl(5, FIONREAD, [0])                 = 0
ioctl(5, FIONREAD, [0])                 = 0
select(0, NULL, NULL, NULL, {0, 10000}) = 0 (Timeout)
ioctl(5, FIONREAD, [0])                 = 0
ioctl(5, FIONREAD, [0])                 = 0
gettimeofday({1205790064, 250624}, NULL) = 0
....

I get at least 100 lines a minute. Can someone explain me what that is 
and if it is supposed to be that way ?

Thanks,
Sebastian
