Vladislav Vaintroub 54534a6984 MDEV-262 : log_state occationally fails in buildbot.
The failures are  missing entries in the slow query log.  The reason for the failure  are sleep() calls  with short duration 10ms, which is less than the default system timer resolution for various WaitForXXXObject functions  (15.6 ms) and thus can't work reliably.
The fix is to make sleeps tiny bit longer (20ms from 10ms) in the test.

# This test suffers from server
# Bug#38124 "general_log_file" variable silently unset when using expression
# In short:
# SET GLOBAL general_log_file = @<whatever>
# SET GLOBAL slow_query_log = @<whatever>
# cause that the value of these server system variables is set to default
# instead of the assigned values. There comes no error message or warning.
# If this bug is fixed please
# 1. try this test with "let $fixed_bug38124 = 0;"
# 2. remove all workarounds if 1. was successful.
