Actually the existing solaris threads support uses the LWP API, not
signals.  However if/when it is merged with linux_threads.c it'll probably
use RT signals as well.

IIRC the original Linux threads code used SIGUSR1 and SIGUSR2 internally,
and RT signals didn't yet work on Linux, which is why SIGXCPU/SIGPWR were
chosen for the collector.
