1760
1761AnyEvent currently installs handlers for these signals:
1762
1763=over 4
1764
1765=item SIGCHLD
1766
1767A handler for C<SIGCHLD> is installed by AnyEvent's child watcher
1768emulation for event loops that do not support them natively. Also, some
1769event loops install a similar handler.
1770
1771=item SIGPIPE
1772
1773A no-op handler is installed for C<SIGPIPE> when C<$SIG{PIPE}> is C<undef>
1774when AnyEvent gets loaded.
1775
1776The rationale for this is that AnyEvent users usually do not really depend
1777on SIGPIPE delivery (which is purely an optimisation for shell use, or
1778badly-written programs), but C<SIGPIPE> can cause spurious and rare
1779program exits as a lot of people do not expect C<SIGPIPE> when writing to
1780some random socket.
1781
1782The rationale for installing a no-op handler as opposed to ignoring it is
1783that this way, the handler will be restored to defaults on exec.
1784
1785Feel free to install your own handler, or reset it to defaults.
