Denis Vlasenko abedaac842 hush: do not reset sighaldlers after fork - instead, prevent them from doing any harm 
if they will be called. saves many sigaction calls on every fork.

Denis Vlasenko c0ea82a457 libbb: revent previous version of "concurrent history updating" 
and replace it with one which does not "snoop" history written
by others. (1) it is what bug 185 needs, and (2) it is less bloaty:

function                                             old     new   delta

Mike Frysinger ddbee974b4 move parse_stream out of ENABLE_HUSH_TICK to avoid implicit decl/build error 2009-03-22 22:48:41 +00:00
Denis Vlasenko 57abf9e947 libbb: make history saving/loading concurrent-safe 
* all history writers always append (not overwrite) history files
* they reload history if they detect that file length has changed since last
write
* they trim history file only when it grows 4 times longer than MAXLINES
* they do this atomically by creating new file and renaming it to old

Unfortunately, this comes at a price:
