That seems to be a result of sloppy programming. That message
is also printed by many "modern" Gtk applications.

Same here, also seems to refer to acroread accessing a Linux
kernel call which FreeBSD's ABI does not implement.

No idea, but I can conform this on my home system too. It's
OS version 8.2-STABLE (from August 2011) i386, and I have
acroread9-9.4.2 and acroreadwrapper-0.0.20110529 installed.
The program is still responsive (as far as you can say this
for bloated programs). In "top", the WCPU value increases until
it reaches 100.00%, and CPU utilization monitor shows a "bar".
When the program is closed, everything goes back to normal.
