 I noticed that while mythfrontend was running, my load average was quite
 high compared to when it wasn't. I tried strace on it and it seems to
 constantly be doing this:

 poll([{fd=3, events=POLLIN}, {fd=8, events=POLLIN}, {fd=7, events=POLLIN},
 {fd=11, events=POLLIN}], 4, -1) = 1 ([{fd=3, revents=POLLIN}])
 read(3, "A", 1)                         = 1
 read(7, 0x14d02c4, 4096)                = -1 EAGAIN (Resource temporarily
 unavailable)
 read(7, 0x14d02c4, 4096)                = -1 EAGAIN (Resource temporarily
 unavailable)


 And lsof reports fd 7 to be:

 mythfront 18164 mythtv    7u  unix 0xffff880085ea7380      0t0  213283
 socket

 Anyone know what might be going on here?
