I can reproduce the problem as described on Mac OS here. After starting
the while loop, switch back to the first session (that is now scrolling
with the SIGINGs) and hold ctrl-c. "leaking fds" appears fairly quickly
and /dev/fd for the affected session does show several new descriptors
remaining after breaking out of the while loop.
The same goes for Fedora and CentOS for the versions of Bash Tycho
listed.
