Then I'll put more words what I meant saying "External conditions might play
its role."

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.
