I have discovered an annoying phenomenon, where after some while (days, weeks)

The good news is that the process itself remains fully functional, but from a
system usage/load perspective, the situation is quite intolerable.
This sounds very familiar to me.
I encountered a similar problem on solaris and was able to make it stop by
putting the following line of code at the beginning of my POE program:
BEGIN { eval "sub POE::Kernel::USE_SIGNAL_PIPE () { 0 }" }
There seems to be a problem with the signal pipe on some platforms, but I
haven't yet done more research to track down what's going wrong.
