 The original behaviour was believed to have been fixed in
 src/sys/compat/linux/linux_stats.c version 1.83

 After the request for feedback (after the above messages), the following
 response was sent but seemingly never made it to PR trail

 "I do not see the original behavoir but I do see a slow leak
 in skype.  Every time a call is made (for example to the
 skype testing service) it leaks 10 to 15 descriptors to
 /dev/mixer0 + some more.  About 75% opens are to /dev/mixer0.
 Still think this is an emulation problem not skype's.
 
 firefox etc. also seem to keep far too many files open.  For
 example firefox has 500+ open descriptors) with 4 tabbed
 windows open.  But in my limited testing can't tell if there
 is a leak.
 
 I am running linux_base-fc-4_7 on a one month old
 freebsd-current."
