[darcs-users] [darcs-devel] PATCH: Delay signal handling until after sensitive operations complete

[daveroundy at gmail.com]

We ignore (and should ignore) sigPIPE, because these errors are
already caught because writes to a closed file handle throw
exceptions.  Moreover, if stderr is closed that leads to a sigPIPE,
and we can't write to stderr anyways.
