Bug#744105: audacity: Audacity burns CPU time

[Hans-Joachim Baader]

Package: audacity
Version: 2.0.5-1
Severity: normal

Dear Maintainer,

When idle, Audacity uses about 2% CPU time needlessly. It doesn't
matter whether freshly started or after closing projects. strace
shows the following repeated endlessly:

recvmsg(3, 0x7fffc8a25860, 0)           = -1 EAGAIN (Resource temporarily unavailable)
poll([{fd=4, events=POLLIN}, {fd=3, events=POLLIN}, {fd=6, events=POLLIN|POLLPRI}, {fd=9, events=POLLIN}, {fd=8, events=POLLIN|POLLPRI}], 5, 0) = 0 (Timeout)
recvmsg(3, 0x7fffc8a25860, 0)           = -1 EAGAIN (Resource temporarily unavailable)
poll([{fd=4, events=POLLIN}, {fd=3, events=POLLIN}, {fd=6, events=POLLIN|POLLPRI}, {fd=9, events=POLLIN}, {fd=8, events=POLLIN|POLLPRI}], 5, 16) = 0 (Timeout)

So the timeout should probably be much higher, especially when
no project is loaded. It should be trivial to reproduce.
