-----------------------------------------------------+----------------------
 When you create a signal_set handling SIGSEGV, and generate a real SEGV
 just after a call to async_wait, the program goes into an infinite loop of
 handling, burning a cpu to 100%.

 It seems that the asio handler writes the signal number into a pipe,
 returns, and is called again indefinitely (Cf the {l,s}trace log).

 I attached a small test to reproduce the problem, strace and ltrace files
 (interrupted after few seconds). Not sure if it's useful though
