[obv] testsuite: read1 fix: gdb.arch/i386-dr3-watch.exp

[Jan Kratochvil]

Hi Pedro,

with "read1" runtest
	[Bug testsuite/12649] New: reproducer for races of expect incomplete reads
	http://sourceware.org/bugzilla/show_bug.cgi?id=12649
and therefore occasionally even during normal runs it will:
	FAIL: gdb.arch/i386-dr3-watch.exp: watch i1 still fits (got interactive prompt)
	FAIL: gdb.arch/i386-dr3-watch.exp: watch i2 still fits
	FAIL: gdb.arch/i386-dr3-watch.exp: watch i3 still fits
	FAIL: gdb.arch/i386-dr3-watch.exp: watch i4 still fits
due to
	watch gap1
	Hardware watchpoint 7: gap1
	Warning:
	Could not insert hardware watchpoint 7.
	Could not insert hardware breakpoints:
	You may have requested too manyPASS: gdb.arch/i386-dr3-watch.exp: watchpoint on gap1 does not fit debug registers
	 hardware breakpoints/watchpoints.
	
	(gdb) PASS: gdb.arch/i386-dr3-watch.exp: delete all watchpoints
	delete
	Delete all breakpoints? (y or n) watch i1
	Please answer y or n.
	Delete all breakpoints? (y or n) n
	(gdb) FAIL: gdb.arch/i386-dr3-watch.exp: watch i1 still fits (got interactive prompt)

Checked in.  Tested on {x86_64,x86_64-m32}-fedora16pre-linux-gnu.


Thanks,
Jan
