Long ago I added some code to yoshimi to deal with denormals (from Jens M Andreasen,
LAD
<http://lists.linuxaudio.org/pipermail/linux-audio-dev/2009-August/024707.html>).
Now I'm wondering if it's actually cool for a synth app or plugin to arrogantly
go
about changing cpu flags underneath other running apps, eg ardour. I'd like to hear
the thoughts of the wise on whether that's a very bad thing for a "minor"
app to be
doing.
cheers, Cal

the OS will restore CPU flags on a context switch. so, doing this in a
plugin is an absolute no-no; doing it in a separate application is
totally fine. i think.

Additionally I think this should be the task of the host, not the plugin if
CPU-flags are concerned. There might be reasons why the host has already
circumvented the denormals by other ways.
