Hi folks,

I got some hangs (deadlock?) between (parallel?) make jobs, top, procps, and 
even ls /proc/*/ when trying to cygport all check curl or look at the process 
statuses when builds hung under Cygwin 3.4.3 and 3.5.0-0.69...

Had to revert to a Cygwin 3.4.0-344 test build from Dec 16 sources to build and 
check curl etc.

Only external differences seems to be recent dll sizes are *MUCH* smaller:

$ ls -glort /bin/cygwin1*.dll
-rwxr-xr-x 1 3588124 Sep  5 05:17 /bin/cygwin1-prev.dll
-rwxr-xr-x 1 3561202 Dec 16 00:33 /bin/cygwin1-test.dll
-rwxr-xr-x 1 3561202 Dec 16 00:33 /bin/cygwin1.dll
-rwxr-xr-x 1 2951221 Dec 16 05:50 /bin/cygwin1-save.dll
-rwxr-xr-x 1 2951221 Dec 16 05:50 /bin/cygwin1-curr.dll
-rwxr-xr-x 1 2940981 Dec 23 03:03 /bin/cygwin1-69.dll

and tars:
-rwxr-xr-x 1 3563651 2022-12-04 06:09 usr/bin/cygwin1.dll cygwin-3.4.0-1
-rwxr-xr-x 1 3563526 2022-12-10 13:12 usr/bin/cygwin1.dll cygwin-3.4.1-1
-rwxr-xr-x 1 3564074 2022-12-11 05:06 usr/bin/cygwin1.dll cygwin-3.4.2-1
-rwxr-xr-x 1 2951221 2022-12-16 05:50 usr/bin/cygwin1.dll cygwin-3.4.3-1
-rwxr-xr-x 1 2940981 2022-12-23 03:03 usr/bin/cygwin1.dll cygwin-3.5.0-0.69...

Anyone seen this issue or anything come to mind to cause or help diagnose this?

Running MS Win 10.0.19044.2364 21H2 patched to date.
