For example, a problem might appear to be fixed when cygwin1.dll restarted, also depending on whether and how rebase/rebaseall was applied. This is particularly true for well-known (among developers) fork-related problems. This however might not(?) be fork-related. I think there is a single occasion when __SIGFLUSHFAST (-39) is sent -- in __main. Is it right after inicialisations ? (When exactly? -- I do not understand). Certainly it is before bash -ci ls opens /dev/tty.
