#14242: Race condition in gap_reset_workspace()

Consider this script `gap_race.sage`:
{{{
from multiprocessing import Process
import time
def rungap():
gap("42")
P = [Process(target=rungap) for i in range(4)]
for p in P:
p.start()
time.sleep(0.1)
}}}
When executing with `./sage --nodotsage gaprace.sage`, this should run
without producing errors. But it doesn't, due to race conditions in
`gap_reset_workspace()`.
