Subject:	limiting strace?, was: failure of unzip and recent cygwin1.dll

Is there a way to limit the size of the strace output _file_, rather
than just the output file buffer, while preserving desired
information?

I previously used strace to debug the problem that 20040213 induced in
emacs 'desktop', therefore in emacs' startup; nevertheless the
resulting strace.out was > 21 MB. Thus I am somewhat hesitant to avail
myself of

(quite the understatement :-) since

* the unzip SEGVs typically occur after 30-60 min runtime

* I have < 5 GB free space. 

Is there a way to limit the file size directly, or to script its
rotation? 

Alternatively, is there a recommended mask setting that will preserve
the desired information, while not blowing out my disk? I'm assuming
'malloc' would be part of the recommended setting: anything else?
