It will certainly hurt.  I suspect it will probably also "just work"
as is usually the case when debugging potential races with strace.

It's probably worth a try, though.  I would just strace each individual
make run, though, overwriting the strace output file every time.

Otherwise, you will fill up your hard disk.

See Egor's recent "how to" on debugging cygwin.  It talks about how
to do this.
