I see now:
	Re: [RFA/testsuite] Reset the timeout duration at the start of each testcase.
	http://sourceware.org/ml/gdb-patches/2010-02/msg00202.html
	commit 501c57da40fd27c8036a5fc995f750b0559272ad

Patch updated.

	* gdb.threads/gcore-thread.exp ($testfile): Match it the .exp
	filename.
	($srcfile): Preserve the original value.
	($testfile): Match it the .exp filename.
	($corefile): New variable.  Substitute it around.
	Use clean_restart.
	($prev_timeout): Remove.
	(load_core): Move core loading into this proc.
	Fix restore of $timeout if load_core fails.
