>Description:

The usr.bin/gdb/t_regress/threads test case started failing on amd64
about a week ago.  The problem started some time between source dates
2019.03.07.18.32.10 and 2019.03.08.23.35.01; a bisection is in
progress but may take a few days.

The test passes on i386.

 Log output from one failure is at:

   http://releng.netbsd.org/b5reports/amd64/2019/2019.03.08.23.35.01/test.html#usr.bin_gdb_t_regress_threads

 The corresponding console output is at

   http://releng.netbsd.org/b5reports/amd64/2019/2019.03.08.23.35.01/test.log

 and contains:

   usr.bin/gdb/t_regress (566/794): 2 test cases
       pie: [9.552284s] Passed.
       threads: [ 53437.7994301] sorry, pid 20284 was killed: orphaned traced process
   [606.395833s] Failed: Test case timed out after 300 seconds
   [616.100450s]

 The following two test cases also started failing around the same time,
 and are also failing on amd64 but not on i386:

   lib/libc/regex/t_exhaust:regcomp_too_big
   lib/libtre/t_exhaust:regcomp_too_big

 That one didn't fail for me on my test run yesterday (amd64 XEN DomU).

   |    lib/libc/regex/t_exhaust:regcomp_too_big
   |    lib/libtre/t_exhaust:regcomp_too_big 

 Those two did however.

 The bisection has now narrowed down the interval where the
 usr.bin/gdb/t_regress/threads test started failing to the following
 commits:

   2019.03.08.20.40.05 christos src/external/bsd/blacklist/lib/Makefile 1.7
   2019.03.08.23.10.52 mrg src/distrib/sets/lists/xcomp/mi 1.203
   2019.03.08.23.32.30 kamil src/sys/kern/kern_sig.c 1.351
   2019.03.08.23.35.01 kamil src/tests/lib/libc/sys/t_ptrace_wait.c 1.100

 Also, the regcomp_too_big tests were already failing before the first
 of those commits, so they appear to be unrelated.  I will file a
 separate PR about those.

 The test passes again, presumably fixed by this commit:

   2019.05.03.07.05.28 kamil src/external/gpl3/gdb/dist/gdb/infrun.c 1.2
   2019.05.03.07.05.28 kamil src/external/gpl3/gdb/dist/gdb/nbsd-nat.c 1.7
