linux emulation file descriptor leakage -current?

This is what happens when I start skype (NOTE: this is *not*
limited to skype -- I see the same problem with a thunderbird
linux binary but linux-firefox & linux-opera work fine).

$ skype &
$ sudo sh -c " while sleep 3; do lsof |grep skype|wc; done"

Is this a known problem or am I in an alternate universe?

I am running -current as of yesterday, with a freshly
installed linux_base-8 and skype.  But this has been
happening for atleast a couple weeks and may be more.

Looking at the lsof output, about a third opens are for a
directory, two thirds are files.  It seems to open over a
hundred directories (all of them multiple times)!  It opens
over 400 files (all multiple times).  Many of these files
have nothing to do with skype!

Doing a truss shows a lot of linux_ioctl() and gettimeofday()
on one skype_bin process and linux_times() and linux_time()
on another process.  Doung ktrace on these processes shows
something totally different (all sorts of syscalls).

Thanks for any help or hints on how to debug this....
