src/tests/lib/libc/sys: t_ptrace_wait.c
Log Message:
Bump the number of threads in LWP t_ptrace_wait*() tests from to 100
This is a torture, but on purpose to catch LWP_CREATED and LWP_EXITED bugs.
The threads do nothing other than calling sched_yield() in a loop.
MAXLWP is now defined to 2048 on all ports.
This change effects the following tests:
- trace_thread_nolwpevents
- trace_thread_lwpexit
- trace_thread_lwpcreate
- trace_thread_lwpcreate_and_exit
