Comment (by Herbert Valerio Riedel <hvr@…>):

 In [changeset:"776a260be009cc27cfeacf298934d544c4e87408/process"]:
 {{{
 #!CommitTicketReference repository="process"
 revision="776a260be009cc27cfeacf298934d544c4e87408"
 Make `cleanupProcess` resistant to SIGPIPE

 Otherwise, `cleanupProcess` may exit prematurely if trying to flush out
 data to the process' stdin handle even though the endpoint has already
 vanished, and fail to complete the cleanup process.

 See also 228297ec53e9ee7a1a6a3c5964ca7e89a6474c9b and #2233.
