Not so sure a backtrace will help much here as SIGIO is an external async 
event.. but maybe.

SIGIO generally indicates there is a filedesriptor opened (or fcntl:ed) 
with the O_ASYNC flag and that I/O is now possible on that filedescriptor.

Another possibility is that you are holding a file lease (fcntl 
F_SETLEASE).

Or that an external process sent you a SIGIO.

Maybe more, but these are the cases I know of.
